1. A computer-implemented method of modifying a finite element mesh, the method comprising:
providing an original-input-orphan-mesh comprising a collection of connected nodes and elements that is separated from a parent geometry on which the collection of connected nodes and elements were originally created;
selecting and extracting at least a part of the original-input-orphan-mesh as an orphan-element-patch-object;
generating faces on the orphan-element-patch-object as a faces-on-mesh-object-geometry;
generating a new mesh patch element based on the faces-on-mesh-object-geometry and at least one changed meshing-parameter, wherein the changed meshing-parameter is assigned to generate the new mesh patch element that is different to a corresponding original-input-orphan-mesh; and
generating an amended orphan mesh by replacing the orphan-element-patch-object of the original-input-orphan-mesh by the new mesh patch element.
