I was having this same error using NormUnbalance. When changing to NormDispIncr, it went away. Any thoughts/updates on this?

Hi selimgunay, Thank you very much for your reply. I have only used dispBeamColumn in the model and haven't used the -cMass option so I think the model has lumped mass. Both of the two cases (assign masses directly to the nodes or assign distributed masses) have the same periods (e.g. T1= 0.23030705...

According to the manual there are several options available in the region command including the '-ele' and '-eleOnly' o...
