Convert an IMAT_FEM to a different system of units
fem = chgunits(fem,from,to)
CHGUNITS converts FEM from one unit system to another, and returns the result in FEM. FROM and TO should be either unit strings or 5x1 vectors of factors such as those returned by GETUNITS. If FROM is not specified, it is assumed to be the current units system returned by GETUNITS.
For coordinate systems, the origin offset is transformed.
For nodes, coordinates are transformed according to the storage (.cs(:,3)) coordinate system type:
| Type | Description | Transformed coordinates |
| 0 | Cartesian | X Y Z |
| 1 | Cylindrical | R Z |
| 2 | Spherical | 0 |
For elements, extra data is transformed according to the element type:
| Category | Type | Extra data transformed |
| 2D | Cartesian | .t, corner thickness |
