Negative Volume problem in ALE model
Hello all
I am working a model which is a tank with water and air.
The Tank and Fluid impact to a rigid wall, and I want to see the stress of Tank and density of fluid.
The container is shell element and fluid were built by ALE.
The model seem fine when model check, but it generate negative volume problem quickly. (on fluid element)
I don't know how to solve this issue, any option or suggest?
