Seal Simulation, Large deforming, Own material not selectable

[Anonymous]

Hi,

We are relatively new to Simulation Multiphysics 2014.

We installed the german version, but some links to tutorials are still not working, looks like they are not finished yet.

Next time I'll install it in english 🙂

Anyway, without training we figured out how to calculate some of our main things in Mechanical and CFD.

But at one point, we always have to give up.

We often have to develop special seals.

So we have large deformations. Ok , we use static stress with non linear materials.

Contact areas often misses, but with other simulations , we usually get it work.

If we try to add a new material in our Material database (own new database), we can choose different types befor starting to fill the values.

We tried several different version, but we cannot see them in the FEM Software if we choose Material and our Database.

So:

1) Ist it the correct way to use static stress with nonlinear Materials for "Rubbers Seals" ?

2) How to get our own material to work in the database ?

regards and happy new year from germany,

Ralf

If your model has surface contact, contact element or coupling element, "MES with Nonlinear Material Model" has better convergence.  To use "Static Stress with Nonlinear Material Model", the model should be well constrained

To use own material, first define the material model in "Element Definition", and then Click "Material" to Edit Material properties.
