LSDYNA Biomechanics Question

LSDYNA Biomechanics Question

LSDYNA Biomechanics Question

(OP)
Hello everyone,

I am a masters student tasked with simulating heart valves in LS-DYNA, and from my research I believe a simulation using ALE elements and FSI coupling has been proven to be the best for this application.

From all of the resources I have found online, I have a decent mesh assembled and I can assign initial velocities to the leaflets which move the way they are supposed to, indicating the basic set up and boundary conditions of the model is working correctly. However, I still have much to correct on my model to accurately represent a heart valve.

How/can I implement a velocity inlet waveform on one side of my model and a pressure output on the other? I would like to input the normal pressure experienced by a heart valve over a cardiac cycle.

How do I fine tune the ALE and FSI settings? I have found very few resources online to learn advanced techniques using these, and all the resources I have found have little to no description of WHY certain cards were implemented. Any teaching resources would be greatly appreciated.

Thanks,
Justin
