I ran the simulation in 2020R2 and when I am using the above mentioned pressure expression, I am getting this error-

Also, the near cell value or conservative value is coming around 0.2 bar and at the boundary I have given -50 Pa. There can be such large difference of 20050 Pa between these value? I am using a refrence pressure of 1 atm.
