I have tried to request EFFMASS > YES in Process for Normal modes, but there are 2 problems : in the output file after the run, there are no mass participation factors calculated. I have to create the request in Solver tab under Parameter.
The other problem is that once I make a request in Process section, I can not know if it is done properly or not, once I am done with the process, there is nothing saved in the Process tab, so I can not know how to undo it, on which nodes have I requested and so, so this tool is not 100% useful. It was better that it left a trace of the operations requested by user
another question about the Modal participation factors, why is it calculated differently and multiple times in my out file for one simple beam ?
