LS-Dyna Adaptive FE-SPH Contact modelling

[Pulkin Gupta]

Hi All

I am trying to simulate the impact of a disc on a target material using Adaptive FE-SPH modelling. For some reason, SPH particles penetrate inside the FE elements without causing any distortions. I have eroding surface to surface contact between elements, sph to sph coupling between sph particles of the two parts and automatic nodes to surface contact to ensure conatct between sph particles and fe elements. For the automatic nodes to surface contact, I have selected nodes of both the parts and for elements I am using a part set ID that includes both parts. Can anyone help how should I approach it further to resolve the issue? I can provide more details of the model, if needed. Thanks in advance.
