The Mesh Generation Process

Following is the general mesh generation process:

  1. Maxwell generates an initial mesh, which includes surface approximation settings. If necessary, the mesher will automatically perform any repairs needed to recover an accurate mesh representation of a model. The solution profile will indicate when mesh repairs have been made, and the results of these repairs will be displayed per object in the mesh statistics panel.
  2. Any mesh operations that were defined are used to refine the mesh.
  3. Using the resulting mesh, Maxwell computes the electromagnetic fields that exist inside the structure based on the assigned excitations.
  4. If you are performing an adaptive analysis, Maxwell uses the current finite element solution to estimate the regions of the problem domain where the exact solution has strong error. Tetrahedra in these regions are refined.
  5. Maxwell generates another solution using the refined mesh.
  6. Maxwell recomputes the error, and the iterative process (solve — error analysis — adaptive refinement) repeats until the convergence criteria are satisfied or the maximum number of adaptive passes is completed.
  7. If a frequency sweep is being performed, then Maxwell solves the problem at the other frequency points without further refining the mesh. An adaptive solution is performed only at the specified solution frequency.
Note: Maxwell does not generate an initial mesh each time it starts the solution process. The initial mesh is generated only if a current mesh is unavailable.
