Hello!
Can anyone help me with this: I made a geometry in AutoCAD, imported it in FE Modeler as .stl, exported as .nas (Nastran) and imported in Autodyn. I must apply to this geometry a concrete material and also I must import a .fil file regarding to simulate a blast in a cavity. I done the .fil file, but I don't know to combine these two parts. Can someone tell me how to do this? Also I have an option to import the geometry in Autodyn as unstructured mesh from ICEM CFD (k file or exp). Thanks a lot! |

I imported the mesh file from ICEM as k file, and this gave me 3 parts: 1 beam, 1 shell and 1 volume. I assigned to each of these parts a Rigid material with 2.5 mg/cm3 and then a Linear material via Initial Condition.
The blast is a TNT blast made following Urban blast tutorial. For this I made an Out Flow boundary, an Ideal gas part (air) and fill this part with TNT (like in the tutorial). My explosion pass through walls and I really don't know what to do. I looked all over the net, but I can't find any answer. So if here is anyone that can help me, please do! Thanks! |

Make sure that you have Euler Lagrange Interaction turned on.

Thanks for your answer Bence, I'm working on it but I don't know the right settings. I'm testing now.
