Title: rigid axisymmetric objects
Post by: sobh on January 26, 2014, 07:27:26 PM

It would be useful to have axisymmetric rigid objects to support all sorts of axisymmetric indentation.

A rigid object can be a set of elements for which all nodes are "fixed" (i.e., have non-zero b.c.).  You can apply a displacement to the nodes (same for all nodes if translation).  Feap also has some rigid body options.  An object can be declared as rigid by inserting the command

RIGID n  !

element list from: ELEM, BLOCk, BLENd, etc.

FLEX

deformable elements

There are limitations on mixing analysis types (especially the transient integrators).

User manual describes some of the options available.

If you have suggestions on what features are needed they can be added to possible future developments.
