Drop Test in Explicit Dynamics

  Hi. I'm new to Ansys. I've been trying to simulate the dropping of a vehicle in water from a height of 3m on Explicit Dynamics, to compute the stresses acting on it. However I keep getting this error message - 'Solver Checks Failed - See Log File for more details' and 'An error has occurred when the postprocessor has tried to load a specific result. Check all messages.' I've tried doing the following:
  
  1) Reduce end time to 0.001 and increase number of steps to 10.
  
  2) Tried Clear Generated Data from Solution tree.
  
  Would be grateful if anyone can look into this issue.

  Have you tried a very simple model, such as dropping a cube into a larger solid plate, just to learn how Explicit Dynamics works? Do that first, then change the larger solid plate to water and see if you can get that to work.

  Yes, I've successfully done that. I tried doing the water drop test again - it seems it is working out only for certain end time-time step time combination.

  Please show an example of what works and what doesn't.
