Hi:

I am solving a fluid structure interaction problem, using ALE, partitioned solver, each time the solid moves, it changes its configuration, with all the coordinate of mesh and dof know,  how could I efficiently evaluate its boundary normal n , so that I could mulitpy p with n to get the neumann boundary condition?

Any advise would be appreciated!

n = FacetNormal(mesh)
Yes, but this is the symbolic notation of n, can I get explicit n each component? also, the mesh does not move for solid mechanics problem, how could I even get normal direction after it deforms?
