WebAs usual get rid of TrialFunctions in favour of nonlinear dependence on Function. You can split a Function on a mixed space into components: w = Function(W) u, p = split(w) F = nu*inner(grad(u), grad(v))*dx + ... Task 5. Add computation of lift and drag coefficients C D , C L and pressure difference p d i f as defined on the DFG 2D-1 website. Webmesh_file: the name of the file containing the mesh information (nodes and connectivity) in a format supported by dolfin. If the user is creating a dolfin.Mesh object within the same script, they can use the mesh object instead of a file name.
