You're welcome. 32GB RAM ought to be sufficient (mesh depending) but all the disc I/O might be causing a memory leak somewhere.
Mechanical is fairly easy (my colleagues who support it will disagree) so just run through the tutorials. Overall, it's always best to have a look at what you need from a simulation then choose the best tool. Pencil, paper and a calculator may be better than a full CFD model in some cases.
