mpco recorder was not created

[Jamildouier]

Dear STKO Team,

I have created a DRM box model following the same approach as presented in the webinar. However, I used different dimensions and a different overall structural configuration.

The model runs successfully and the analysis is completed without any errors. However, at the end of the analysis, no MPCO file is generated.

I have also tried running the analysis with different numbers of processors: 2, 6, 10, and 14. In all cases, the analysis runs successfully, but the same message appears in the black output box, and no MPCO file is created.

Could you please help me identify the reason why the MPCO file is not being generated?

The following message appears in the black output box:

Thank you very much for your assistance.

That error message means that OpenSees crashed.
if it crashed soon before starting the analysis, it makes sense: no MPCO to write to.
Otherwise, the only reason for not writing an MPCO files would be that maybe you defined the recorder after the analysis
