Dear Dave,

I tried for Different Cases, and I followed your statement also I made static run for every time when I change the config file... But I didn’t find any changes in INCLUDED MASS DATA RESULTS.

1.In Config file for missing mass ZPA I selected spectrum. And I checked for extracted also.

In spectrum I changed 33HZ corresponding acceleration value to 1000, 2000, 3000 very big values. So CAESAR should takes the ZPA as 1000 (I think).
But there is no change in included mass data results. I checked the % Force added.

2.In spectrum if I give up to 10 hz but my cutoff frequency is 33 hz, what CAESAR do for calculating forces in between 10hz to 33hz (what are the acceleration value CAESAR used from 10 hz to 33 hz)??

Whether it Extrapolates and calculates the ZPA for 33 HZ or
it takes same value of 10 hz, for in between 10 hz to 33 hz to calculate forces…??

please help me....
