Parallelism calculation method

Hello

I need to perform a parallelism with external material calculation method how can I do?
I can't find a compute option for parallelism. In the help it seems to me that I found that flatness and parallelism are in Chebyshev.
Can someone give me some clarification on this? PC-DMIS 2019R2 version
Thanks in advance

My best regards
