Blast Simulation

Dear community

I have to run blast simulations.

 

I use the Eulerian Lagrange Approach with material Law51, Iform 11. (Drucker Prager yield surface used to model soil)

The FS-Interaction is modelled by contact type 18.

 

I got the failure: id 167 negative rho.

How do I avoid this error?

 

Where do I find deeper explanations about the contact type18 and the material law51?

Is there a bench mark or example regarding detonation in soil with interface to structure?

 

Thanks in advance for sharing experiences.
