Is GRF-option needed for Analysis tool with CMC state data?

[Hide Kimpara]

Hello,

I'm wondering to add GRF option on Analysis tool. I proceeded RMA and CMC analysis for some gate analysis with GRF data. During RMA and CMC analysis, I always added GRF data. However, should I add GRF data during Analysis tool? CMC state data was selected as a motion data on Analysis tool. Of course, the results of joint reaction forces are different with or without GRF data. Which is the realistic analysis for joint reaction force or reaction forces?

Best regards,
Hide

I believe that if you want to analyze afterwards with the Analyze Tool that you should add the same external forces as you did in CMC to get correct results.
