Make changes to an existing mesh. The possibilities for modifications are:


* reorienting edge meshes used to apply pressure,


* check the orientation of the normals on the shell elements,


* reorienting the meshes of a monolayer of joint elements,


* update the mesh based on a deformation calculated previously,


* in a mesh with a crack background, move the middle nodes of the edges touching the crack bottom to a quarter of these edges,


* translate a mesh,


* impose one or more rotations of any axes on a mesh,


* generate a symmetric mesh with respect to a plane in 3D or a line in 2D.


* calculate the curvilinear abscissa along a line made up of line elements (SEG)


* change the coordinates of the nodes randomly

Produces a mesh-like data structure or changes the data structure (re-entering operator).
