The idea that is on my mind is basically two parts. The first part is that that an explosive charge (say TNT) inside a structure will be detonated that will cause shockwave and gas pressure inside the structure, so I need to determine the pressure it exerts to the confining wall (CFD this will be done in openFOAM). Then the second part would be the response (strain and stresses to be in deal.ii) of the walls including cracks,damage, fractures or failures (if there are any, due to the high pressures) using FEA. So basically, I wanted to couple this two procedures, CFDxFEA in order to have a more exact simulation and result which results to a dynamic remeshing or anything like this for every time step until the explosion fades. I would like to ask if deal.ii is capable of simulating failure due to separation of the elements? This will be done in blastFOAM-preCICE-deal.ii. Hoping for your response at your convenient time. Thank you and more power!
