It is also possible that your model uses a constant timestepping scheme. In order to understand how this works, enable the Equation View, and look at the implementation of the Dirichlet condition (in this case, a prescribed temperature):. In a previous blog entry, we introduced meshing considerations for linear static problems.One of the key concepts there was the idea of mesh convergence as you refine the mesh, the solution will become more accurate. The convergence semi-angel was 35 mrad with an annular recording range of 80-210 mrad. Syracuse University is an equal opportunity/a?rmative action employer with a strong commitment to equality of opportunity and a diverse workforce.
