Using WSMLink for simulation of Modelica generating wrong file paths

Alachew Mengist
Posted 12 years ago

Hello,

I used WSMLink to simulate modelica model from Mathematica. However, The simulation settings file (.sim) is generating wrong filePath and resultFilePath.

See an example below.

 <?xml version="1.0"?>
 <!DOCTYPE simulation>
 <simulation version="1.0"
    name="BouncingBall"
    start="0."
    end="10."
    stepSize="0"
    outputSteps="-1"
    tolerance="1.e-6"
    method="dassl"
    filePath="BouncingBall.exe"
    resultFilePath="BouncingBall.mat">

From the above resultfilePath is " BouncingBall.mat" .However, The actual result file is "32608BouncingBall_1.mat"

Why resultfilePath refers to the " BouncingBall.mat" while the generated file is with file name "32608BouncingBall_1.mat"?

The Simulation settings file generated is also attached below.

As noted in the other thread ( http://community.wolfram.com/groups/-/m/t/339700?p_p_auth=q7hVqLPX ), if you are using version 3 there is no way to specify or retrieve the name of the result file.

You can continue using the functionality in WSMLink to read data from the simulation result, see WSMSimulationData documentation: http://reference.wolfram.com/system-modeler/WSMLink/ref/WSMSimulationData.html

Hi,

I want to simulate and plot a modelica model via pythonica (Python package for the sane interface between Mathematica and python via mathlink).

Here is the pseudocode

   import pythoinica
   m = pythonica.Pythonica()
   m.eval('Needs["WSMLink`"]')
   m.eval('Import["' + mofile + '",{"ModelicaModel"}]')
   res = m.eval('WSMSimulate["' + self.name + '",{' + str('0') + str(',') + str('10')+ '} ]')

It worked fine and generates the result file, simulation settings and simulation executable. However I want to read the result file , load it and create a plot.
