HI,
I am just install latest nightly build OM 1.9.3-dev1036

I am try overrideFile  with this command. -overrideFile c:/omfiles/a.txt            OMEdit gives error.

assert | debug | <p>simulation_input_xml.cpp: usage error you cannot have both -override and -overrideFile active at the same time. see Model -? for more info!</p>

I also try -override Cell1.SOCini=0.95 , then i got below error.

stdout | warning | <p>each command line option can only be used once: -override</p>

I also try without -override still get error.

How can override file?

Thanks

Hi,
At the windows, I create test.mo model  and run Model with OMShell (.mos script)
OM create test.exe file.

I need to know capability of test.exe file.

test.exe -output=variable  is giving me variable value of  simulation stopTime. How can get value at different time?

Thanks

Hi There,
I do assign boolean  value to variable with when command.
such as below sample.

  when condition1  then

    x = true;

  end when;

and then i want to re-assign new value with new condition.

  when condition2  then

    x = false;

  end when;

But OM give me this error.  " Error: Model is structurally singular, error found sorting equations "

How can re-assign  x  value after when condition.

Thanks

Oki

HI There,
I want to override combiTable output with change integer x value. But i got few equation error.   It is looks ok to me.
How can fix this. or is there any suitable  approach for change  prescribedTemperature inputs?

Thanks

Hi There,
I want to compare VoltageSensor vMeter.v with 26.5 volt raference voltage.
If vMeter.v>26.5 then do something else ....

But with this code vMeter.v always act like bigger then 26.5. I know during simulation vMeter goes to below 26.5.

What's wrong?
Do you have any idea?

Oki

model lab2b

  parameter Real xPnom(start = 1500);

  Real xIdc;

  Modelica.Blocks.Interfaces.RealInput Pneed;

  Modelica.Electrical.Analog.Interfaces.NegativePin pin_n;

  Modelica.Electrical.Analog.Interfaces.PositivePin pin_p;

  Modelica.Electrical.Analog.Sensors.VoltageSensor vMeter;

  Modelica.Blocks.Tables.CombiTable1D Tnd1(tableOnFile = true, tableName = "leff", fileName = "C:/p/deff.txt");

  Modelica.Electrical.Analog.Sources.SignalCurrent SD;

equation

  Tnd1.u[1] = Pneed / xPnom;

  xIdc = Pneed / vMeter.v * Tnd1.y[1];

  if vMeter.v > 26.5 then

    SD.i = 10;

  else

    SD.i = 0;

  end if;

  connect(SD.n, pin_n);

  connect(SD.p, pin_p);

  connect(vMeter.n, pin_n);

  connect(vMeter.p, pin_p);

Hi There,
I am looking for PowerSystems library.
I want to experience  PowerSystems.Examples.Spot.AC3ph.Transformer example.
But i got equation error. The model has 212 equation(s) and 226 variable(s).

Did anyone simulate this example?

Thanks

I want to use this png at the web interface

Oki

I also noticed; I was connect linux  via ssh.
When i try to run OMPlot local terminal , i got all plot at the screen.
Still i am looking for solution via ssh save plot to png

Thnaks
Oki

By the  way  i just noticed; linux also have  OMPlot. But when tried with below cmd

OMPlot --filename=.... --plotAll

i got OMPlot cannot connect to X server

actualy i am interesing save to png file. Not plot to screen

oki

Hi,
I am using linux distro.
How can save mi simulation result  plot  to png file?
At Windows there is OMPlot.exe but at linux  i don't know.

Oki

with ubuntu 14.04   I installed openmodelica w/o any error.
Thank you.

Oki

Alright,
I will freshly install Ubuntu 14.04.2 LTS , then i'll try installation procedure again.

Thanks anyway,

What's wrong ? Can samobody help please?

Oki

Thanks anyway adpro

Oki

Hi adpro,
ModelicaUserGuide 1.9.1 Chapter 5(page 83)

I tried model.exe -interactive -port 10500  (this call server machine)
Then  try to communicate with client machine via socket connection. 

My goal is getting simulation result from  server machine using socket connection

oki

I got it.

According userguide.pdf i can communicate model.exe with socket/port connection, right?
How can i communicate model.exe?

Thanks
oki

Thanks adpro,
with  Model.exe -override stopTime=0.2 -output R1.v      model_res.mat file not effected right?
Only with simulation  model_res.mat file  will change.

Oki

First of all, Thanks for your answer,
My simulation timing: startTime=0, stopTime=1

model.exe -output R1.v     then i get,

time=1, R1.v=.0.234567..

How can i  value of R1.v at  0.2 second?

With override R1.R value we do not need simulation again for new result value  right?

How can plot (R1.v) ?

Thanks

Oki

Hi there,
With  OMShell  simulation("model.mo"), OM creates  model.exe file.

How can i use  model.exe?

How can get specifit value of parameters at specific time?
How can override model.exe?

Thanks

Oki

sure, thanks anyway

Because; i want to keep same type of  variables  in one file. For example, i got 8 resistor,capacitance and SOCini.
I want to change dynamically only resistors inside  for loop it is easy to manipulate files. Thats why.

Oki

How can  overrideFile with two files?

I tried this line. I do not got any error, but only a.txt override. b.txt not proceeed.

simulate(allnew,stopTime=6000,simflags="-overrideFile a.txt,b.txt");

Thanks
Oki

Hi,
I can read or write fie OMShell with below syntax w/o error.

readFile("c:/loop/test.txt");
writeFile("c:/loop/test.txt");

But, I want to delete file with below command,

deleteFile("c:/loop/test.txt");

file  does not deleted.

Do you know why?
Thnaks

Oki

I mean i know print only stdout,
When i try to write array to file i got nothing,

for i in 0:6 loop

arr[i]:= abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

end for;

writeFile("c:/loop/log.txt",String(arr[0])+"\n",append=true);

log.txt  is never create w/o any error. But for testing purposes i try;

for i in 0:6 loop

arr[i]:= abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

end for;

writeFile("c:/loop/log.txt",String(11)+"\n",append=true);

log.txt   created and inside data 11.

arr := fill(0.0,6);

for i in 0:6 loop

arr[i]:=abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

print arr[i];

end for;

print max(arr);

when run script i got; Error: Parse error: Only function call expressions may stand alone in an algorithm section
before use arr() i have to define or something?

Oki

    Thanks again
Oki

Ok, How can append result value to array?

for i in 0:6 loop

v:=abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

end for;

got it thanks
Oki

Hi,
Modelica scripting language have math library such as ABS(value), MAXIMUM(array)  e.t.c. ?

Thanks

Oki

Thanks, I just find out second ago ))

Oki

Hi,
I want to execute/run  OMShell with .mos script file   from windows cmd  console or high level  software.
How can i do that?

I am asking like this;
OMShell.exe -open c:/test/a.mos

Thanks
Oki

Hi,
I am using OMShell.
After simulation how can i get and override CombiTimeTable  filename?

Thanks

Oki

Thank you,

I want to understand for loop. I run this script with  runScript("test.mos")
result of this script
"0

100
"
I am excepting 0- thru 100 count.  Wht only start and stop value print screen?
Oki



test.mos

j:=0;

for i in 1:100 loop

j:=j+1;

end for;

j;

Hi again,
I found pdf file. But,

for i in 1:18 loop val(Meter.v,i); end for

this code suppose to be  print val(Meter.v,i) value but not,

What's wrong this code?

Oki

Thank you sjoelund,

So, i want to compare two different parameters inside loop.
I try something like this but it is not working,

for i in 1007:1016 loop i:=i+1; val(Meter1.v,i)-val(Meter2.v) ; end for;

Is there any  documents explain more control about   for, loop, if, while, wend e.t.c.

Oki

Adrian,
Also i am looking for OMShell it is very usable.
Does OMShell have   for next / while wend  type of controls?

Oki

Thank you Adrian,
I think val() only working with .mat result.  For .csv not implemented yet.

Oki

Hi,
I am freshly install OMPython. My OS is win7.
I have simple code such as below.

from OMPython import OMCSession

OMPython = OMCSession()



print OMPython.execute('loadModel(Modelica)')

print OMPython.execute  ('loadFile(\"C:/loop/test.mo\")')

result = OMPython.execute('simulate(test)')

OMPython.execute("plot(meter.v)")

print result

I have 3 question.
1) I read print result file ..... 'resultFile': '"C:/loop/test.mat"'}  but, there is no test.mat file in c:/loop folder.

2) How can get result file as csv file not mat?

3)If simulation stop time 100 then, how can i get specific time result on screen like meter.v (time =33) ?

Thanks

Oki

Hi,
I want to change some cell parameter such as internalResistance , chargingCapacity   e.t.c  from Model.

I define parameter like this:

parameter Real newRo=0.003;

and change cellParameter like this;
Rs = ED_EES.CellRecords.Components.Resistance(R0 = newR0);

When i made this change i got below error.

Error: Component cp11.Rs of variability PARAM has binding ED_EES.CellRecords.Components.Resistance(cp11.newR0,  ....

What's wrong with this?

My MSL is 3.2.1

OMedit 1.9.1. r22929
What is MSL?

I am working on Win7.  loadSource section is very quick. But  .readRealParameter() is not.
URI mean file path on PC right: In this case "c:/oki/test.txt"

Hi,
I am try to read  variables  from file.

Here is file:
test.txt
a = 2;
b = 3;
c = 4;

Here is the Code:
parameter String file = Files.loadResource("c:/oki/test.txt");
  parameter Real a = Examples.readRealParameter(file, "a");
  parameter Real b = Examples.readRealParameter(file, "b");
  parameter Real c = Examples.readRealParameter(file, "c");

Simulation is extremely slow. PC read this three variables  almost 7-9 seconds.
Finally , variables read but some errors.

Do you have any idea what's wrong?

Hi,
How can  change booleanStep startTime variable via realExpression value?

Thanks

Hi,
I want to modifiy OM Model. Model have  a realEXpression  user enter value before simulation. I want to change realExpresssion with time table.
How can i do that?




Thanks

Hi,

batt5.mo

I am trying simple battery pack discharge circuit as i attached.

There is less equation but more variables I don't know  why?

Do you guys have any idea?

Thanks

Hi,
I want to use logic to boolean converter. For logic source  i am using Electrical.Digital.Source.Step object. Also i use Electrical.Digital.Converter.LogicToBoolean component. When i try to connect two pin  i saw Connect Array message (Enter Index ). I try enter1 but i got:

"[C:/OpenModelica1.9.1/lib/omlibrary/oki/test.mo:7:50-7:60:writable] Error: Type mismatch in binding before = 1, expected subtype of enumeration('U', 'X', '0', '1', 'Z', 'W', 'L', 'H', '-'), got type Integer.
Error: Error occurred while flattening model test

What i suppose to enter?

Hi Ceraolo,
I use  Analog.Source.TableCurrent. But i got below error.

[C:/OpenModelica1.9.1/lib/omlibrary/Modelica 3.2.1/Blocks/Sources.mo:2080:5-2080:19] Error: Model is structurally singular, error found sorting equations
17: 0.0 = tablecurrent1.signalSource.a * time + tablecurrent1.signalSource.b;
18: algorithm
.....

Here is my test circuit.

batt2.mo

Could you please check device, whats wrong with

Thanks
Oki

Hi Ceraolo,
There is a component called  tableCurrent. I this what i am looking for. Thanks anyway...
OKi

Hi Ceraolo,
Thanks for your answer.
I know stepCurrent component.  But i need  something with more  step like this.


For example i can read from table time,current rate e.t.c

Is there ayy way to do this?

Thanks

Oki

Hi,
I have question about OM EnergyStorages library.

I designed basic discharging circuit atteched below.

batt1.mo

I want to change CC load discharging current during to simulation. I mean ; first 500 second  dicharging 20 amps, then next 500 second discharging current gonna be 40 amps. Is that possible?

Thnaks
