Simulation failed ?

Simulation failed ?

Feb-05-10 15:32:27

Hi,

I'm a brand new user of OM, (and of this forum apparently) and while running through the tutorial I'm surprised to see that no single 'simulate' command seems to work.  I always get resultFile= "Simulation failed."  See below for an example.

Anybody an idea how to solve this?
I just installed the 1.5.0 RC2 version on windows XP

Thanks a lot for your help,
Roel


>> loadFile("C:/OpenModelica1.5.0/testmodels/dcmotor.mo")
true

>> simulate(dcmotor,startTime=0.0,stopTime=10.0)
record SimulationResult
    resultFile = "Simulation failed.
"
end SimulationResult;

Small addition: The DrModelica examples in OMnotebook didn't work either.
I decided to uninstall OM 1.5.0 RC2 and I installed RC1 instead, now it works...
So the problem seems to be linked to RC2.

regards,
roel

It works fine in RC2

>> simulate(dcmotor, startTime=0, stopTime=1, numberOfIntervals=500, tolerance=1e-4)
record SimulationResult
    resultFile = "dcmotor_res.plt"
end SimulationResult;

The problem was that the first version of 1.5.0-RC2 I uploaded on the website was missing 2 header files.
You can re-download the file from: http://www.ida.liu.se/labs/pelab/modeli … ndows/rc2/
This will get rid of the simulation problems you had.

Cheers,

I've installed Openmodelica in Ubuntu 10.04, and after doing the first User Guide examples, an error appears:

>> simulate(dcmotor,startTime=0.0,stopTime=10.0)
record SimulationResult
    resultFile = "Simulation failed.
Error: Error occured while flattening model dcmotor
"

Anybody knows about it?

Thanks,

Jose

Openmodelica works fine in Ubuntu 10.04!

The error reported in my previous comment probably was due to some "copy paste" wrong type, so I'm sorry.

Jose
