New question #143185 on DOLFIN: https://answers.launchpad.net/dolfin/+question/143185
I solve the Navier-Stokes-Brinkman equation with fenics and get the velocity u and the pressure p as result: (u,p) = problem.solve().split() At the end of the program, I'd like to write u to a xml-file, but using the code: velocity_file = File( "velocity.xml" ) velocity_file << u.vector() causes the following error: velocity_file << u.vector() RuntimeError: *** Error: You are attempting to access a non-const vector from a sub-Function. Using the code: solution = problem.solve() velocity_file = File( "velocity.xml" ) velocity_file << solution.vector() works, but I'd like to know if I can store only the velocity u in a xml-file.
