Trilinear form in navier stokes stationary eq

Question

Hello everyone,

I am interested in assembling trilinear form in NS eq. (stationary), starting from

a(u,v) + c(w,u,v) +b(p,v) = F(v)
b(q,u) = 0

I would like to solve the problem with the method of the fixed point, but I do not understand how to assemble the trilinear form.

Best regards,
Francesco

Did you take a look at the tutorial? The example there is unsteady, but the assembly of the linearized convective term is in principle the same as for fixed point approaches.
