  I want to make a simulation of compression/pressure rise taking place inside screw compressor, due to rotation of rotors. which solver should i use? is it correct to use immersed solid in CFx or if anyother plz guide.

  i have two concerns regarding this:
  1- the pressure rise shown in contours is neglible where as a high value was expected.
  2- the ANSYS CFX Solver modelling guide tells that immersed solid doesnt cater for the compression effects very well and also not works with total energy or thermal energy models. but i have to enable the total energy model otherwise how would the compression be taken into account by the solver?
