Hi,

This should not happen. By default omc stores everything in the current directory where it is ran.

You can do a mos script:

// -start script

cd();  // display the current directory

loadFile("YourModel.mo"); getErrorString();

simulate(YourModel, stopTime=2); getErrorString();

// -- end script

cmdline> /path/to/omc script.mos

The generated YourModel_res.mat file should be in the current directory where you ran omc.

You might have just ran .mo files (which do nothing, just displays the flatten code) or generates code with +s.
And then you searched the temp directory and found .mat files made via OMEdit.

odrpo, thanks.  This time outputs are sent to the omc bin\ folder instead of the working directory at e:\OM\Tests\. .  My be something is wrong with the file path declarations in the script

Here is what I have:
mo path : E:\OM\Tests\cmlTest.mo
mos path: E:\OM\Tests\cmlScript.mo

cmlScript.mos file content:
// -start script
cd();  // display the current directory
loadFile("e:\OM\Tests\cmlTest.mo"); getErrorString();
simulate(cmlTest, stopTime=2); getErrorString();
// -- end script


When I run commandline, everything is thrown to bin\ of omc. 

What I have done is this:
path/to/omc e:\OM\Tests\cmlScript.mos .  On windows console, I have to provide the full path of the mos file to generate the output. otherwise, it couldn't find the file

So it doesn't work if you cd e:/OM/Tests/ and then run path/to/omc cmlScript.mos?

I did the following in the cmlScript.mos but it failed to process

// -start script
cd(e:/OM/Tests/); 
loadFile("cmlTest.mo"); getErrorString();
simulate(cmlTest, stopTime=2); getErrorString();
// -- end script

It appears working if I put the mos in a batchfile


AMong the files generated, I see one file 'Output' which is empty.  Why is that?

Hi,

You need to do this:
1. have both cmlScript.mos and cmlTest.mo in E:\OM\Tests\
2. run from command line:
    > e:
    > cd E:\OM\Tests
    E:\OM\Tests> C:\OpenModelica1.9.0\bin\omc.exe cmlScript.mos

This will generate all the files in E:\OM\Tests

Note, you will need to change cd(e:/OM/Tests/); in cmlScript.mos to cd(). Empty cd() just displays the current directory, does not change it.
The cd("path") command takes a string, so if you want to change directory via cd in your script you would need to do it like cd("e:/OM/Tests/");

output.log is the result of the running of the generated cmlTest.exe for simulation. If is empty then is OK, there were no errors during simulation.

adrpo, very nice,  thank you very much.

adrpo, excuse me for initiating this thread.  The above mos and command line instructions work for a simple text based model.  How about if the mo file is a package containing several models and if we want to run a specific experiment?

Hi,

In you script:
loadFile("path/to/Library/package.mo"); getErrorString();
simulate(Library.Path.To.Your.Model);  getErrorString();

Should do it.

Thanks a lot. Very helpful.
