" CONTACT INTERACTIONS BETWEEN NODE-BASED SURFACES ARE INVALID"

[Pk19]

While Creating a node-based surface with SPH (Abaqus) using PC3D particles with an orphan mesh. I encountered a problem "CONTACT INTERACTIONS BETWEEN NODE-BASED SURFACES ARE INVALID"
I would be massively grateful if anyone can give me some directions

 

[FEA way]

The question is how exactly you define that contact. Check the documentation chapter "Smoothed particle hydrodynamics" (paragraph "Interactions") to see how to do it. It has to be a contact interaction between a node-based surface (particles) and an element-based/analytical surface. General contact is usually the best approach.
