ADAMS/SOLVER 1

[josefl9]

Hello,

This is kind of a general question, but I've had a lot of trouble finding an answer.

Are there any tips/rules of thumb to use when modeling with MSC ADAMS that would result in a more numerically stable solution, or that would allow the solver to converge faster? So far, in every model I've worked with, small changes in parameters such as contact forces/contact damping, result in huge differences in solution time and results.

I know this is kind of a general topic, but literally any small tip might help me.

Thanks in ADVANCE

JK

Unfortunately the Solver often needs fine tuning, and the defaults aren't necessarily sensible. In particular it is worth investigating which solver you are going to use SI1, SI2, original or modified, and all the other parameters used to control your run. You might consider attending course 703B
