The following illustrates an overview of the FEM process. | |

|
From Design Model to FEM |
|
The example below demonstrates a one-to-one relationship between the
design model, the Proxy CATPart, and the Finite Element Model. The data
used to generate the mesh model (support geometry and constraints) comes
from the Proxy CATPart.
For instance, at this stage, the Proxy CATPart along with the FEM is self-sufficient for assembly analysis purposes without relying on the original Design Model. |

Formulas and Equivalent Dimensions |
|
The three parameters below are provided in order to facilitate the multi-edition for all the mesh parts.

|
In the relation set, five Equivalent
Dimensions are created. They control:

Mesh Quality Improvement |
|
While Creating FEM on a very challenging model, the result of the
Create Mesh command may some times require some manual
adjustments. For instance, for a complex shell, adjusting the constraint sag manually could reduce the number of internal edges to be considered as the mesh constraint. By default, the constraint sag is set to 0.0. This implies that the surface will be constrained with all of its internal edges, if any. For more information on how to improve the mesh parts quality you may refer to Advanced Meshing Tools User Guide, Surface Mesher in Analysis. |
