Parallel calculations to reduce computing

Is there an easy way to make the calculations more parallel to reduce computing time?

I thought about creating a parallel for loop with C#, but I have no previous experience with that and maybe there is something implemented in the API.

The API is tightly connected to write/read files and parallel computing is not recommended.

If you want to try, I would suggest to do a parallel loop creating several instance of FemDesignConnection and work with those in parallel.
