Fluent Volume-Integral

DinoDino Member

Hi,

I have two questions please:

How can I get the mass of a species in a porous media within a UDF. The problem is, Fluent Volume-Integral of the gas fraction does not consider porosity and give me wrong results for the mass? 

The second question please, how can I recall the generation rate of that species in a porous media in Kg/m3.s? is there anyway?

 

Thank you,

    You can create a custom field function to get the mass of component in the porous media. UDF you need to to sum up C_YI(c,t,i)*C_R(c,t)*C_POR(c,t)*C_VOLUME(c,t) in the whole domain. Here you need to take care of parallel processing (by using some global reductions macros). The kinetic reaction rates of each reaction in Fluent are already scaled with porosity and accessible for post-processing.
