I am trying to model the strain generated by inserting an electrode device into brain tissue. I've had some success in doing this in ANSYS Explicit Dynamics. Here's a link to a GIF showing the penetration.
My issue is that I had to do a very fast insertion (10 m/s) in order to have a faster computation time (~18 h). The actual insertion speed is on the order of 0.1 mm/s, which ends up being 5 seconds of simulation. 5 seconds of explicit dynamics simulation is days of computation on my computer! My question is, can I do this sort of slow penetration/ballistics model in ANSYS transient dynamics or some other implicit model? Or am I stuck with Explicit dynamics and the super long computation time?
