Hey guys, well the title really explains it all. I have a insertion reaction force curve that i expect, but unfortunatly i keep getting this peek in the Force Reaction at single step where there is penetration involved. Question is, any ideas. Tried mesh refinments ping ball rejoins etc etc

Thanks alot Carlos, thats exactly what i was referring to. Too bad, cause alot of my simulations start off needing a small time step and then don't really require all those little iterations. Anyway, Thank you :)

Thank you for your reply. I usually do turn off auto time stepping, and indicate myself the initial time step, minimum time step and maximum time step. But my problem with the program, is that if it reaches the minimum time step during the solution, and converges, why doesn't the program...

Hello Gents, I ususally utilize smaller increment time steps to gradually place a load on a solid for example. My question is......... Why doesn't ANSYS after utilizing the minimum time step you indicated and converging through that step, ............attempt to use a larger time step size to...
