Compilation of flat model
Compilation of flat model
Hi every one,
First, thank you for the attention and help you'll give to this post.
Quickly :
-----------
- I'm using OMC 1.9.1.beta.1 compiler
- I want to generate C files from *.mo files
To do this :
- I generate a flattened model *.mof from *.mo files
- I try to generate some C files from the *.mof, but i have a compiling error.
This error occurs in the first line of the *.mof declaring a parameter :
parameter Real someModel.param1(fixed = false);
OMC compiler rejects the dot (".")
More precisely :
----------------------
- I have a master model (in "master_model.mo") declaring submodels :
model master_model
subModel1 instance1() ;
subModel2 instance2() ;
....
equation
<Some equations...>
end master_model;
- I generate a "master_model.mof" with the command :
/some_path/omc +showErrorMessages +d=failtrace +d=disableSingleFlowEq master_model.mo subModel1.mo subModel2.mo ....
No problem to get this "master_model.mof"
- I try to generate C file from "master_model.mof" with the command :
/some_path/omc +simCodeTarget=C +showErrorMessages +g=Modelica +d=initialization +d=failtrace master_model.mof
and i get a compiling error :
{"[/a_path.../master_model.mof:2:26-2:26:writable] Error: Missing token: SEMICOLON", "SYNTAX", "Error", "2"}
When i look at master_model.mof, here is what i see :
class master_model
parameter Real subModel1.param1(fixed = false); // Error on this first line because of the dot
parameter Real subModel1.param2(fixed = false);
<some other declarations....>
equations
<some equations....>
end master_model;
The dot on line 2 is rejected.
What did i do wrong ?
The presence of this dot at this place in this file seems illogical
since a declaration should be done with a variable or paramater name without dot,
as in most language.
Besides, since OMC compiler created the *.mof, this file should have the right
syntax and be usable to create C files with the same OMC compiler.
Thank you
Re: Compilation of flat model
The .mof file is not intended to be usable for re-compilation. It is only for diagnostics.

Re: Compilation of flat model
You probably want to use the +s flag to generate simulation code.

Re: Compilation of flat model
some of my simulation failed and I have this error :
[:0:0-0:0] Error: [b]Failed to open simulation result /tmp/OpenModelica_maryam/OMEdit/BuildingEnergySystems.CaseStudies.TemperatureControl.Thermal_equivalent.Rooms.RoomsThermalSimplifiedWithAppliances_res.mat: Too few rows in data_2 matrix
and my output is :

Re: Compilation of flat model
Here is the actual error,
Code:
assert | debug | division by zero at time 0, (a=0) / (b=0), where divisor b expression is: heatPump_ConstantCOPheat1.W Debug more
Clicking on Debug more should take you to the equation causing the error. Fix division by zero error in your model.

Re: Compilation of flat model
Hello All,
I am using Dymola software 2017 and I have a concern regarding a question about reading the differential equations (nonlinear and linear) of a model using the dsmodel.mof file.
I have a Thermal power plant (with 104 continuons time states), which I cannot read its complete system of equations through its dsmodel.mof file. I am finding it complex to interpret and figure out these equations from the script in the file specially the non-linear system of equations.
Can someone please guide me to properly read them specially the nonlinear part ?
Pls. find attached mof-file for your review.
Thank you all for your help in advance
