I had already used the 'Adjust to touch'.. but the simulation was running when I constrained the upper plate and restricted its movement in X AND Z direction. But I saw that the femoral head was penetrating into the upper curved plate. Only one error was there which read:
Then I did what was given in the error. I switched the large deformation as 'OFF' then I rerun the simulation but there was no change, the penetration between curved plate and femoral head is still there. It seems that the results are fine but can you confirm that.
