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

"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)

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

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.
