A number of numerical schemes are available for the solution
of the mesh displacement diffusion equation. In many cases the default
scheme is appropriate, but in some situations mesh folding can be
avoided and improved mesh quality can be obtained by using a different
scheme. The expert parameter meshdisp diffusion scheme controls which numerical scheme is used. For details, see Discretization Parameters. Setting meshdisp diffusion
scheme to 3 can be helpful if the
mesh folds unexpectedly at sharp corners or if uniform mesh deformation
is expected but non-uniform deformation is observed. The figures below
show an example of using different mesh displacement diffusion schemes.
