      Hi Subhu,

      Check the time step imposed in the model, which will increase the model mass.

      Reduce the imposed time step value. Optimally it is advisable to have 2-3 % mass error.


      PS: Always post queries in the forum. We will not be notified when you post queries in your profile and so we will miss to reply.
