@negativevolume Yes, I checked it before the simulation running. I checked those elements marked with negative volume, and they don't appear any disto...

Thank you very much for this. The point for my model is that the disc not a rigid body. So, there are conflicts for defining the translate and rotatio...

Defining translation and rotation motion for a rigid body, and then the plate's motion driven by the rigid body.

@lsdynastudent You can attach your K file here, I will help you to check the issues.

@lsdynastudent Hi, I think there is a problem with parts coupling. When you use ALE for blasting modeling, three parts are inevitable: explosive (ALE)...

@negativevolume Hi, thank you very much for your kind reply. I tried some models with elements failure in implicit solution. For the fracture toughnes...

Hi, did you make it?

@negativevolume I am so sorry that I didn't make myself clear. I made a simulation about slope blasting to shed light on the issue. First, the implici...
