What’s the precision (single or double) of ICEM-CFD output mesh (.msh format) for the Fluent solver?

  My simulations usually require very fine mesh (like 10 million tetra elements in a complex cavity of about 3*5*10cm size). I checked the manuals of ICEM-CFD and they do not mention if single or double precision is used when outputting mesh for the ANSYS-Fluent solver (.msh format). And there is no option to set the precision in the write-output window. Could anyone help check with it? Thank you and I appreciate it!

  Single or Double precision is for the Fluent solver. You should be able to use any mesh generated on either of these solver precisions. You will get this option when you launch the Fluent session, and not during the mesh export. Once you launch the Fluent session as either single or double precision, you should be able to read your mesh file normally.
  
  Thank you.
