Mspost automatically opening, files err.out

There was an error rendering this rich post.

Hello I am reaching out because I am a bit confused.

I have made a model of a car including 4 flexbodies. When I run the analysis (in batch mode via matlab) , its done in something like 2 minutes.

BUT while it is running it creates .err.out files (which are being deleted after the analysis is finished). Also, after the analysis is finished, I see in task manager mspost running in the backround.

The thing is that even though the analysis takes 2 minutes to complete, bacause of the mspost and the temp files created, the analysis ends up taking more that twice the time.

Is this normal ?

Hi @Pantelis_Myrio ,

I did receive confirmation that MotionSolve uses the log completely for any error reporting.

These err_<int>.out are created by compute console to log any failure before starting the Solver.

It is normal and will be cleared if the run is completed and even if you kill the process in between it should be empty.

Hope this helps!

Hi @Pantelis_Myrio,

I was able to view the .err out files when running a separate model. They were also deleted after the analysis was complete. My assumption is that if any errors are written to the .err.out file, they would be pasted in the .log file and the .out file is deleted to reduce the amount of output files. Let me check and I will get back to you.

When referring to taking more than two minutes to complete. I'm assuming you mean more than two minutes to get the results? Once the analysis is finished, depending on the size of the models, some additional time is needed to compile the result files (.plt, .abf, .mrf, .h3d)

Best,

Hello Christofer and thanks for your response.

Yes, i found out afterwards that mspost was writing the h3d, plt files that I requested and was taking a lot of times cause of the size of them.

About the .err.out, I havent noticed any error in my log files, just warnings and the results were fine too.
