One of the exercises from my postgraduate course in simulations done in Ansys with use of APDL. This time another solver than Ansys in use.
Short informative overlook at hyper-elastic analysis capabilities of Mecway, with CalculiX solver usage. Mecway v5BETA was used with 1000 nodes limit, which is the case why mesh is so coarse. In analysis, 2 parameter Mooney-Rivlin material model was used. Rigid body motion, contact and self contact were used. Non-linear analysis type. Results are for reference only!
What you can observe here is:
- high non-linearities (large deformations)
- self contact
- rigid body motion
Some of the so called CAD FEM systems are struggling with such demanding conditions. CalculiX is very powerful engine but requires additional pro-/pre- processing tool or a bit of patience, knowledge and fond for simulations ;)
