I've been try to model explosion of TNT in Air(Eulerian model) and steel plate(Lagrangian) for finding the plate central node displacement and compare with Conwep blast analysis result.
without considering the head effect on air pressure due to explosion,the node displacement is very low than conwep result.
with considering the heat effects, this error was reported:
Eulerian nodes cannot be shared between different sections. The nodes have been added to the node set named "ErrNodeEulSecIntersect".
The nodes in node set ErrNodeEulSecIntersect are referenced by elements in an Eulerian section and a rigid body, a rigid body reference node, or another section.
who can help me to correct this model?
oh
when i tick the adiabatic consideration in step modulus, and the solid element cant consider heat, this error was created.
so, i dont know what type analysis can used for explosion in air with influence blast pressureT temp effect and disp output in Eulerian - Lagrangian simulation.
