Export the mesh in a memory representation.
Parameters:
- auto_groups (boolean): parameter for creating/not creating
- the groups Group_On_All_Nodes, Group_On_All_Faces, ... ;
- the typical use is auto_groups=False.
- overwrite (boolean): parameter for overwriting/not overwriting the file
- meshPart: a part of mesh (:class:`sub-mesh, group or filter <SMESH.SMESH_IDSource>`) to export instead of the mesh
- autoDimension: if *True* (default), a space dimension of a MED mesh can be either
-
- - 1D if all mesh nodes lie on OX coordinate axis, or
- - 2D if all mesh nodes lie on XOY coordinate plane, or
- - 3D in the rest cases.
-
- If *autoDimension* is *False*, the space dimension is always 3.
- fields: list of GEOM fields defined on the shape to mesh.
- geomAssocFields: each character of this string means a need to export a
- corresponding field; correspondence between fields and characters
- is following:
-
- - 'v' stands for "_vertices_" field;
- - 'e' stands for "_edges_" field;
- - 'f' stands for "_faces_" field;
- - 's' stands for "_solids_" field.
-
- zTolerance (float): tolerance in Z direction. If Z coordinate of a node is
- close to zero within a given tolerance, the coordinate is set to zero.
- If *ZTolerance* is negative (default), the node coordinates are kept as is.
