Mesh Controls

You can adjust the mesh controls to achieve the following goals in your simulation:

Improved performance by implementing a coarser mesh globally.
Improved results by implementing a finer mesh for a part or body.
Improved results around holes and other areas of interest in the model.
Improved results by adapting the mesh throughout the simulation.

Element Size Control

You can specify the exact size of the elements in a part. The element size is then used to calculate the absolute and proportional sag values to determine the mesh refinement around features.

Mesh Refinement Around Features

You can specify the minimum number of elements in the mesh around the holes or other features in your model. A higher number yields smaller element and better results around holes and curves. You can define one global value for this setting and then specify a different density for a specific part.

Note: If your element size is relatively large compared to some holes in your model, the mesher might create fewer elements around those holes than the minimum number you specify.

Adaptive Remeshing

When the solver is unable to converge to a solution, the app can perform an adaptivity pass to remesh your model. The adaptivity pass either refines or coarsens regions of the mesh to reach an acceptable level of accuracy for the solver to converge. The app can perform multiple adaptivity passes until the solver converges. Each adaptivity pass is expected to improve the quality of your simulation results, even when large deformation or loss of material occurs.

Adaptive remeshing is available only for the global mesh.
