Mesh Control Parameters

Mesh control refers to specifying different element sizes at different regions in the model. A smaller element size in a region improves the accuracy of results in that region. You can specify mesh control at vertices, points, edges, faces, and components. Mesh control is not available for beams.

To access the Mesh Control PropertyManager, right-click the Mesh icon and select Apply Mesh Control.

Mesh Control Parameters

The mesh control parameters are:

  • Element size (e) for the specified entities

  • Element growth ratio (r)

Assuming that the element size used for meshing an entity is (e), the average element size in layers radiating from the entity will be: e, e*r, e*r2, e*r3, ...., e*rn . If the calculated average element size of a layer exceeds (E), where (E) is the Global Size , the program uses (E) instead. The mesh radiates from vertices to edges, from edges to faces, from faces to components, and from a component to connected components.

To apply mesh control to mixed types of entities:

  1. In the Simulation study tree, right-click the Mesh icon and select Apply Mesh Control.

The Mesh Control PropertyManager appears.

  1. In the graphics area, select the entities for which you want to apply mesh controls.

  2. Under Control Parameters, do the following:

    1. Select a unit and type a value in the Element Size box .

    2. Type a value in the Ratio box .

  1. Click .

To apply mesh control to multiple components:

  1. In the Simulation study tree, right-click the Mesh icon and select Apply Mesh Control.

The Mesh Control PropertyManager appears.

  1. Click the FeatureManager design tree tab .

  1. In the FeatureManager flyout, select the components to which you want to apply mesh control.

The selected components appear in the Selected Entities list box.

  1. Under Selected Entities, select Use per part size.

The software assigns an optimum element size for mesh control to individual components based on their volume. Move the Mesh Density slider towards Coarse to increase the element size by a factor of 2, or towards Fine to decrease the element size by a factor of 0.5.

  1. Click .
