Hello all,
I am interested in running simulations investigating ultrasound wave behavior in fluid-filled porous solids (could be metals or biomaterials like bone). I was able to successfully run the 'fluid flow past a flap' example on this forum. I was also able to propagate an ultrasound wave in a copper plate in the FEBio Structural Mechanics module with results comparable to those of a reference publication [Chen, Hanxin, et al. "Simulation of ultrasonic testing technique by Finite Element Method." Prognostics and System Health Management (PHM), 2012 IEEE Conference on. IEEE, 2012.]. However, when I attempt to run a similar simulation using the Fluid-FSI module of a copper plate with a water filled circular pore, the simulation does not converge/gets hung up and I still cannot determine why. Am I setting up the simulation conditions incorrectly? Is it more theory related, where perhaps I didn't realize FEBio is not well-conditioned for the type of simulation I want to run? For some reason I am unable to attach the files, so I can email the simulation files if anyone is interested. Any help or suggestions would be greatly appreciated! Thank you!
