Run getErrorString() to get error-messages.

Hi,

Have you tried a restart after installing? Or at least logout/login.

To test more I would suggest to run omc from command line:

> c:\OpenModelica1.9.0\bin\omc script.mos

where script.mos contains:

loadModel(Modelica); getErrorString();

simulate(Modelica.Blocks.Examples.Filter); getErrorString();

Then see what the output is and let us know.

sjoelund.se, i think OMShell runs getErrorString() automatically after each command.

I would also suggest to install the latest nightly build:
https://build.openmodelica.org/omc/buil … ly-builds/
as is far better than 1.9.0.

Cheers,

Thank you both for the fast replies! I didn't expect that.

I ran omc just as you said and got:

true
""
'"C:/OpenModelica1.9.0//share/omc/scripts/Compile"' is not recongnized as an internal or external command,
operable program or batch file.
record SimulationResult
    resultFile = ""
    ...
end SimulationResult
""

(note i copied that by hand so I probably misprinted a few letters)

I checked and the file exists, but has a .bat extention.
also I had to add .exe when i ran omc:

> c:\OpenModelica1.9.0\bin\omc.exe script.mos

It seems that the problem is that the computer doesn't ignore the filename extention where it should.

Did you install a custom shell that could mess with extensions not being auto-completed?

Maybe .exe and .bat file associations are corrupted somehow.
You could run a tool like this (or search google for something else):

to get them back.

I found that the enviroment variable PATHEXT of my user was just ".py;.pyc". so I add ".com; .exe;.bat" and it worked.
Then I got another problem, the simulation .exe file did not work (it gave some error that had to do with mingw), I solved it by copying the system PATH to the user PATH.

I think the problem was this: I installed python(x,y)  only for my user, and it created PATH and PATHEXT variables for this user, that override the system variables.

now everything works, but I feel that there is something wrong with my eviroment variables. do you think this is because of a bug in python(x,y)?

Unfortunately, I have no idea if the python installation broke the Windows XP handling. Maybe.
Anyway, I'm glad that you found out what the problem was with OpenModelica.

Hello everyone,

I have a model named "test.mo" and I am trying to simulate this model with omc command from cmd window. When I use the omc command I receive an error which says "Failed to build model: test". But I simulate the model with OMEdit without any problem. There is nothing wrong with the model and I do not understand why when I try to simulate it with omc command it says model cannot be built. I would be extremely grateful if you could help me out current/smile

Best,
Pouya
