Hello, I am simulating a h2 /Air diffusion flame in a gas turbine combustor under 1 Mpa pressure. please where to introduce 1Mpa ( prepdf, operating pressure in flunet ?).

Thank you

hi able

u can specify 1Mpa at inlet BC.

In prepdf, you have to set the pressure for the fuel and oxidizer.

These will be automatically used as the operating pressure (once you hook the pdf file to fluent, you will not be able to modify the operating pressure, you will see that the operating pressure box is disabled)

Hi balmiki My bc are velocity inlet type, no pressure field is available ???

if pressure at the fuel and oxidiser inlet available try the problem while converting velocity inlet to pressure inlet.
