Dear STKO community,

I'm working with my model in OpenSees and I'm trying to generate an mpco recorder to be used with STKO post-processor. As long as I was using version 3.2.2 of OpenSees I had no problem, but since I switched to the version 3.3.0 I am no longer able to generate mpco recorders obtaining the following error after running the analysis (that is blocked):

commands.cpp - : mpco NOT FOUND
WARNING No recorder type exists for recorder of type:mpco-1

Is there anyone who can help me?

Thank you.

Unfortunately, the MPCO recorder does not work on 3.3.0. You can either use:
1) an older version, HDF5 database was implemented in the 3.0.0
2) prof. Tarque's version: https://drive.google.com/file/d/1ETGQ3Y ... 5Mk7C/view

Bear in mind that the next official version of OpenSees will support the MPCO and HDF5 database.

Regards

So we just have to wait for the new version.

Thank you for your fast and accurate reply.

Kind regards,
Nicola

As we said meanwhile you can use prof. Tarque's version which is 3.3.0.

The MPCO recorder issue persists even after I have tried prof. Tarque's version of solver kit with STKO versions 2.0.6 and 3.0.0. kindly help!!!
