Error in ANSYS Explicit Dynamics

AI Thread Summary
The discussion revolves around troubleshooting an error in ANSYS Explicit Dynamics when simulating the impact of a cricket ball on a bat using custom materials. The error message indicates a failure in solver initialization, which does not occur when using steel as the material. To diagnose the issue, it is suggested to create custom materials based on steel without altering properties and test their functionality. If the custom materials fail, the problem lies in the custom material process; if they work, then the issue is likely due to incorrect properties in the custom material. Additionally, there is a query about where to input specific material properties like bulk modulus and shear modulus in ANSYS or Abaqus.

TL;DR Summary
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.
 
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
