12.2 Computing deviation of mesh from geometry

Product: Abaqus/CAE

Benefits: You can now verify how well a native mesh conforms to the boundaries of its parent geometry. This enhancement enables you to ensure that the generated mesh is a sufficiently accurate discretization of the original geometry, and it is particularly useful when the original geometry contains small holes or regions of high curvature.

Description: The geometric deviation factor is a measure of how much the element edges in a mesh deviate from the original geometry, as shown in Figure 12–1.

Figure 12–1 Geometric deviation factor.

You can compute the geometric deviation factor of elements in a native mesh by using the mesh verify tool. When you verify the quality of selected elements, Abaqus/CAE displays the average geometric deviation factor in the message area for all of the elements in your selection that lie along a curve or a face. When you verify the quality of a part or one or more part instances or regions, you can highlight the elements that have an edge whose geometric deviation factor is greater than a user-defined threshold value.
