This is an animation of a validation model for IMPETUS Afea Solver. For more information, go to http://impetus-afea.com/.

Description

This model shows that one single cubic hexahedron has the ability to represent the resulting torque from torsion of an elastic square section with high accuracy. All formulas used in this validation test can be found at [reference].

The model consists of an elastic beam, clamed at one end and attached to a rigid body at the other end.
