GeometryManipulations
geometrical modifications of boundary elements files read
Sometimes, it is necessary to geometrically modify geometry entities. That can be done by
GeometryManipulations can be a list. It will be executed in the order as they appear.
Actions like scale, offset etc. can even be repeatedly be applied.
Example:
The geometry manipulations are applied to the node points. The topology connections describing the elements are not touched.
