Hi, I'm solving a steady state heat transfer problem derived from the example : onelab.info/wiki/Heat_equation_with_Dirichlet_boundary_control The solver get the element-based temperature field. How can I get the nodal field ? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
