Unit in UDF
hi everyone, I am working with micro channel flow. Let the height of the geometry of my channel is 1.2 micro meter. I know I have to convert this unit to meter by scale conversion. But when I will write UDF then if I have to use the value of height then I to write H=1.2 or H=0.0000012? Thank you. Tajul

Re: Unit in UDF
All the values our UDF communicates with the Fluent solver must be in SI units. If you retrieve a value from Fluent, it will be in SI unite, and if you give a value to Fluent, it will be interpreted as it wee in SI units.
Internally, Fluent always uses SI units. Even if the GUI is set to use PSI for pressure, all the values will be translated into Pa. Such a translator does not exist between your UDF and the solver. best regards, Laika, still orbiting |
Re: Unit in UDF
Dear Laika, Thank you for your valuable suggestions. You are right but I am in problem whenever I use SI unit for channel height. I am explaining this in my next message. With best wishes to you Tajul
