FEM MeshNetgenFromShape/pl

Description
For a finite element analysis the geometry needs to be discretized into a FEM Mesh. This command uses Netgen (which needs to be installed on the system) for calculating the mesh.

Depending on your operating system and your installation package Netgen might be bundled with FreeCAD or not. For further information see FEM Install.

Usage

 * 1) Select the shape you want to analyze. For volume FEM this needs to be a solid or compsolid. A compsolid is necessary if your part is made from multiple materials. (A compsolid can be created with the BooleanFragments command.)
 * 2) * Press the button, or
 * 3) * select the option from the menu.
 * 4) Optionally, edit the parameters.
 * 5) Click the  button to make a mesh, or  button to make a mesh and close the dialogue.

Properties

 * : Maximum size of the element in mm.
 * : Second order elements contain more nodes per element. Usually, it is enough to use rougher mesh to obtain same solution precision as with the first order elements,
 * true (default); second order elements,
 * false; first order elements.
 * : Defines how fine the mesh should be.
 * : Defines how much adjacent elements can differ in size.
 * : Defines the minimum number of mesh segments per edge.
 * : Defines the minimum number of mesh segments per radius.
 * true (default); applies optimization algorithm to improve mesh quality,
 * false;
 * false;
