UDF Surface to Volume Ratio
 

Hi All,

Is there a way to implement a UDF to alter the surface-to-volume ratio in space of a porous media?

Thank you,
GF

Volume to Surface Ratio
 

Could you be able to find a way ?
Thanks.

Its fairly simple - you can use DEFINE_PROFILE but only if you want it to change from iteration to iteration. Else, use an expression or a profile file.
