The forum discussion centers on troubleshooting an error in ANSYS Explicit Dynamics when simulating the impact of a cricket ball on a bat using custom materials. Users report a 'Solver initialization failed' error when custom materials are employed, while simulations with steel proceed without issue. To resolve this, it is recommended to create custom materials based on steel properties and verify their functionality. If errors persist, the issue likely resides in the custom material properties, necessitating careful review and adjustment.
PREREQUISITESThis discussion is beneficial for simulation engineers, materials scientists, and anyone involved in finite element analysis using ANSYS or Abaqus, particularly those troubleshooting material-related errors in dynamic simulations.
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.jrmichler said: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.
