  I am getting a floating point exception when modelling multiphase for pressure difference of 30 bar with methane as 0.97 volume fraction and water as 0.03 volume fraction in ansys fluent for a valve. I have considered ideal gas as density model for methane

  Might happen. As you are not giving any details I just stick to reducing time scale.

  I have created a mesh with first layer thickness as 0.8*10-7. Surface tension as 0.065N/m for phase interaction. Already reduced the time scale for pseudo transient to 0.01. Turbulence model as k epsilon scalable

  How long does it take the flow to pass through a cell?
