I'm trying to input a Torque vs. Angular Velocity function curve into my Motion Analysis study and it seems I'm limited to values under approximately 4000 in-lbs as if I input values greater it either doesn't accept the value or crashes the analysis. It does this whether I manually input the Data Points or import a *.csv file. I tried changing units to metric but there again I seem to be limited to approximately 500 N-m, however, the exact maximum value varies and isn't consistent. Sometimes I can get it to work with larger values if I input small values then edit them after I perform an initial analysis with the smaller values. I'm not sure I have much confidence with the outputs at this point though.
what version and service pack of the software are you using?
if you manually enter the value for torque does it accept it? can you post a screenshot of where you're entering the value and maybe a sample part. (just a stick rotating around a hole with the torque on it)
