Hi Samyak,

  Are you able to provide details of what your analysis settings are? An explicit analysis doesn't guarantee speed, it depends on the time step calculated based on the smallest element in your model. So, What is the total end time and your time step? 

  Your mesh looks extremely refined which could be causing problems. Partition your model only simulate only the area of interest. 

  Also, We have a few verification examples in the help that you might find helpful, these are from MAPDL though.
