I've tried to do the IDA analysis for frame structure but IDA curve is not somehow satisfactory and even the openseas is crashing during running at higher scales. How can I sort out the issue?

While modelling the 3D Frame structure consisting of steel beam and column, I'm getting an error message even after incorporating torsional parameters. ----->>>>>> error message: WARNING - no torsion specified for 3D fiber section, use -GJ or -torsion My main script----------------------------------...

Thanks a lot, @selimgunay

I'm doing time-history analysis of Four-storied MRF frame structure. I've defined the several required parameters and successfully done several analyses such as modal analysis, static analysis, pushover analysis. But during this time history analysis, I've been facing convergence issue from past one...
