It's probably because you did not create the model in STKO pre processor.
Local axes are not obtained as an output from Opensees (they are not available for all elements), so we use STKO to generate a support file for the mpco recorderer, with the extension .mpco.cdata.
It contains several ...

Hey Kesavan,

Thanks for your reply.

The axes shown in the first figure are the local axes while the axes shown in stko are the global axes.

If the red is the X-axis in stko and the green is Y-axis then the global axes match between opensees and stko as shown bellow:

Dear STKO team,

I created a model in openseespy and I am trying to visualise the gravity results in STKO but I am a bit confused.

The orientation of the beam in Global X and Global Y is made using the following commands:
op.geomTransf(BTransfType, BTransfTagX, 0, -1, 0, "-jntOffset", *dI, *dJ ...

Thanks STKO team. That solved the issue and now I can use MPCO recorder.

I am trying to add MPCO recorder to openseespy. I followed the steps in the link here https://opensees.github.io/OpenSeesDocumentation/developer/build.html. It got it compiled. I then changed the installed opensees.pyd to the compiled one. But I get error "Failed to import openseespy on windows ...

Can you please tell me what are the instructions to include MPCO in openseespy.

Is the hdf5 library compiled into professor Tarque's version?
Yes, the MPCORecorder is included.

If not, could you please tell me how this could be done?
If you want to compile your own version of OpenSees and/or OpenSeesPy including the MPCORecorder, please follow the instruction here https ...
