Desr STKO team
I am a beginner in STKO, in the last two weeks I have learned the basic skills of modeling and analysis using STKO, with the help of the STKO team I have successfully run my static analysis model, thank you again. Now I am trying to do a dynamic analysis of my model, according to the video material I replaced the loads with the original static model and changed the settings in the analysis steps, after many failures I still can't get the desired result, as the picture shows it can't be analyzed any more, so I would like to ask for some help from you guys, if you can help me to find out where the mistakes are and give me some suggestions to change them I would be grateful. I would be grateful if you could help me to find out what is wrong and suggest some modifications.
Regards

Re: Dynamic analysis failure
It's because you are using a partitioned mesh, but the analysis settings are wrong.
When your model is partitioned for parallel computing, you must use the Parallel Numberer + MUMPS.
Also use the same constraint handler in both analysis (why are you using Lagrange Multipliers in the dynamic analysis).
Last note:
I don't understand what are you trying to do with both the uniform excitation and ground motion. Read the OpenSees documentation about them to understand how to use them
