      i am running explicit dynamic simulation of single particle impact simulation but the problem is i am keeps on getting time step too small and the solution stops and gives an error. This is dominant when i increased particle velocity to higher values i have tries all the possible ways I know to sort out this. but no luck.ni used mesh size (1/20) of diameter of particle and my particle diameter is 40 micrometer. Mesh method quad nand i want to run simulation for 150ns ( tried till 80ns but getting error)n
