Frequency Analysis

[metalboy]

Hi there,

New user to abaqus here. I'm trying to run a frequency analysis in abaqus/cae (to find the best step time..). Firstly, i hope that this is the correct thing to do before running an explicit analysis...secondly i have received an error reading "node set assembly pickedset234 has not been defined". Does anyone know if this is to do with my constraints?

Thanks for any help you can offer!

Sounds like a load or BC that you have defined is referring to a no -onger existent region. Perhaps you modified the geometry? Edit your Loads/BCs and check the applied regions...
