Hello I am working on laminar flow module for a simple straight channel. I am using mesh of very high resolution for my computation. It is taking really long time. Is there is a way to set the simulation such that it uses multiple processors and runs faster?

Save your mph, exit the GUI and from a terminal run:

comsol batch -inputfile my_file.mph -np 4

where -np 4 is for the number of processes to use.
