**quad_to_lin

Description

This command reduces the integration order of a mesh to linear. This command can be conveniently applied using the Zquad_to_lin script front-end.

Note

There is also currently (Z-set 8.3 and newer) a mesher lin_to_quad to go from linear to quadratic. However, curved surfaces will be unrealistically modeled with facets. If there is the possibility of running with quadratic meshes, the basic meshing operations should be set to produce a quadratic mesh, and the mesh should be linearized before use.

Syntax

The command will be activated simply with the command name.

**quad_to_lin \(~\,\) [ *param_file list-of-files ] \(~\,\) [ *elset elset_name ] \(~\,\) [ *keep_orphan_nodes ]

*param_file

is an optional list of nodal parameter files (temperature, …), that will be “linearized” accordingly. Resulting files will be named with a .lin suffix.

Note

Alternatively, a mesh to mesh transfer of nodal fields can also be used.

*elset

restricts the operation to the given elset.

*keep_orphan_nodes

to keep orphan nodes (default=false).
