Hyperelastic Analysis (Mooney-Rivlin: MATHP and MATHE; Ogden) Error in F06!

[Curcubeu84]

Hello,

I am doing an analysis on shoes made of Hyperelastic material like EPDM and EVA.

I created the material an isotropic with Hyperelastic costitutive model and Mooney-Rivlin.

If I insert the values of the coefficients manually in the form for the MATHP the model works while if inserted the value of the coefficients in the MATHE form it doesn't work and give me this fatal error in teh f06
*** USER FATAL MESSAGE 2016 (TA1)
NO MATERIAL PROPERTIES EXIST.
0FATAL ERROR
The same problem is given if I use the OGDEN coefficients.

Where is the problem?

Here the picture of the two forms and the F06 with the fatal error.

I've had the same error before. I tried defining a complex material, only to find out the element I tried to apply the material to did not support that complex material.

It is worth checking your .bdf or .dat file and ensuring all of your elements have a property and material associated with it.
