The amplitude and direction of such forces is known a priori. In particular it is independent from the deformation of the underlying material. Such forces also strongly depend on the chosen mesh desnity. Changing the mesh usually requires a complete redefinition of these forces. text/html 2016-03-30T13:23:04+00:00 Anonymous (anonymous@undisclosed.example.com) http://metafor.ltas.ulg.ac.be/dokuwiki/doc/user/conditions/displacements?rev=1459344184&do=diff Prescribed Displacements Basic usage [Beginner] A displacement can be prescribed to a set of nodes with an evolution function and the object LoadingSet: loadingset.define(target, field, ampl=0.0, fct=None, incr=INCREMENTAL_LOAD) loadingset.define(target, field, ampl, fctMulti, fieldList, incr=INCREMENTAL_LOAD) text/html 2022-04-28T15:17:03+00:00 Anonymous (anonymous@undisclosed.example.com) http://metafor.ltas.ulg.ac.be/dokuwiki/doc/user/conditions/rotations?rev=1651159023&do=diff Prescribed Rotations Loading in cylindrical frame : prescribed rotations - radial displacements (around a moving axis) Displacements and rotations imposed with respect to an axis are extensions of imposed displacements (translations) and are used to rotate/move a set of nodes around an axis, which can be in motion too.
