HOW TO CALCULATE THE COEFFICIENT PERMEABILITY VALUES,CONSTANTS VALUE LIKE C1,C2,n VALUES. HOW TO CONSIDER THE PROBLEM,TAKE AS VOLUME OR SOLID? SO PLEASE SEND YOUR SUGGESTIONS & IDEAS. YOURS FRIENDLY, SUBRAMANI.J

So from experiment find out these values and directly assign in STAR. Hope this helps.
