I used a deformable body and defined its material property as TNT using JWL EOS. After partial simulation I am getting an error message that elements are excessively deformed, and result shows increase in volume of TNT. Actually I wanted the TNT to get exploded into small fragments.
Hi Hamid
Please find the attachment. Actually I wanted to model a coupled euler lagrangian analysis.For instance a plate and explosive would be inside an eulerian domain (air).Once the explosive blast takes place I was willing to model the pressure waves. As a start to this , I just modeled a explosive using JWL EOS but facing problems.
hi
i cant find the AIR material in your model.
after define the model and property of material,assemble and set position, in interaction all model must be coupled .
so the in predefined, you must be material assignment and initial stress define.
