Slow Computation/Simulation Time

Hello all,

i am working on a model of the human lumbar spine including ligaments and discs for my masters thesis. I am using 60 virtual cores for the solver. Most of the times the total simulation time is about 30 to 40 minutes. Is there a way to speed this up? My supervisor is also using RADIOSS with 60 cores but it only takes about 5 to 10 minutes. Anyone have an idea what could be the issue? Also, i heard there is a way to split up the cores to run several simulations simultaneously, how does this work exactly? I apologize in advance for any potentially stupid questions, i am still new to FEM.

Cheers, Tim
