[Solved] BB model ans Abaqus

Hello to all, Hello Jorden

im using the neo-hookean model with a C10 =0.5 and a bulk modulus (1200 Mpa) for simulating an elastomer specimen. i would like to consider the hysteresis effekt (im used the paramter of BB model S, A, m, c) as well but theres allways the following error:

Hybrid elements can be used with the hysteresis model only when the accompanying hyperelasticity is fully incompressible.

Please can you tell me, How correct this error ?

That is easy. Either set D1 > 0, or use Hybrid Elements.
