2d axis symmetric explicit simulation

      i am trying to analyze 2D impaction process of hip implant ( head over neck) with the

      impaction force = 4KN

      base fixed support

      axis symmetric analysis

      but first off all it is giving the error that force boundary condition cannot be applied

      secondly when using the pressure boundary condition the solution is immediately terminating giving the error of solver error to high

      this issue gets always

      In the Pressure BC, did you ramp up the pressure over a period of time?
      What is the solver error that was immediately shown when you ran the model?

      i have to analyze the simulation over 0.0007 second with the pressure magnitude varying over this time interval in sinusoidal manner. and error that is terminating the simulation is (solver error.; energy error too large)
