Hello all,

I am relatively new to NEK5000, but have learnt the basic configuration on running a case via gmsh mesh, par and usr files.

Now that I wanted to solve species equation thereby couple through momentum equations. I have attached images of equations to be solved (3 to 5).

I will be glad if anyone can give me clues on how to work on this in usr file (I think I am sure I need to modify usr file- usrf section).

Thank you

Ananth Narayan
