Access Granular Temperature in UDF

Hello,

I am writing some code to modify the solid pressure. But granular temperature is required in the formulation of solid pressure. Definitely, I can not calculate the granular temperature in UDF because I may use PDE to solve granular temperature. However,I can not find any utility that can access granular temperature from through UDF. Could anyone give me some advice?

Thanks,

Gavin

Re: Access Granular Temperature in UDF

"I may use PDE to solve granular temperature." Why could this cause you can not access the ganular temperature. I nearly know nothing about PDE, but I am very familiar with Fluent UDF, maybe I could help you. You can email to me, I would like to know something about PDE. Thanks!

Hello Joey,

By PDE I mean partial differential equation which is coded in Fluent 6.2.

Thanks,

Try using either of these two macros.

C_GT(c,t)

C_STORAGE_R(c,t,SV_GRANULAR_TEMPERATURE)

Re: Access Granular Temperature in UDF

Thank you so much for your valuable information, us.

Can I ask you another question? What is the difference between SV_GRANULAR_TEMPERATURE and SV_GRANULAR_TEMPERATURE_AP. I guess SV_ means that Solver Variables although I can not find any reference in UDF manual.

Thanks,

Gavin

Re: Access Granular Temperature in UDF

Not sure Gavin. I also guess the same about SV. I would say, UDF manual is just 10% of what it should be. It doesn't contain all the required information.
