Granulation and Dissolution

The simulation of the dissolution of a multicomponent porous medium (including virtual granules) can be summarized into the following steps  

Start from an initial structure—defined by phase functions f r, t — 0). 

Solve a convection-diffusion problem in the fluid phase surrounding (granules) or penetrating (porous media) the object of interest. 

Update phase functions according to local dissolution rates. 

Check the connectivity of the solid skeleton—remove disconnected solid phase if present.
