[porous_media]

Hi everyone,
i'm simulation in-situ leaching in fluent. i have a 2-D rectangular geometry. in the reaction penal of fluent (in porous zone) i encountered with "Surface-to -Volume ratio" i can not understand what value should i assign or how to calculate it. please help me in this issue
thanks

The ratio which you have to calculate is the surface of the interface between the porous media and your fluid divided by the total volume of your porous media.
