Error in ANSYS Explicit Dynamics

[OmkarE11]

TL;DR

Help with explicit dynamics.

I am tring to simulate impact of cricket ball on a bat. Whenever I try to simulate with custom materials it shows an error like 'Solver initialization failed. See the log file.' But when I carry out with steel as the material it works fine. Please help.

My experience is with Abaqus explicit rather than Ansys explicit, so take this accordingly. You have a model working with a steel. Then I would create a custom material from that steel without changing any properties. If that worked, I would create a a second custom material, and specify all properties identical to the same steel. If either of those two custom materials fail, your problem is in the custom material process. If both of the custom steels work, then the problem is an incorrect property in your custom material.

Can you tell me from where I can add bulk modulus, instantaneous shear modulus, long term shear modulus and decay constant? I am Ansys or Abaqus.
