Hi everyone,
I am doing airplane impact problem. In my simulation, I need to have an airplane and a wall. The material of the wall is concrete. I utilized the LS-DYNA concrete damage model (keyword *MAT_CONCRETE_DAMAGE) to describe the wall and also added *DEFINE_CURVE for tabulated strain/pressure data. I kept getting error messages: *** Error 20450 (STR+450) Material model 72 (CONCRETE_DAMAGE) Only eos 8, eos 9 and eos 11 are valid *** Error 20018 (STR+18) input phase completed with 1 fatal errors please check messag file I would be thankful if anyone could give me some suggestions of solving this prooblem. Thank you in advance. |
