How to modify the the diffusive exchange coefficie
 
In the LECTURE 5: THE MATHEMATICAL BASIS OF PHOENICS of POLIS, there is The Generalized Form for sigle phase conservation equation solved by PHOENICS, I don't know how to modify the diffusive exchange coefficient for for phi, when phi stands for the electrical potential or other dependent variable ? Althrough the PHOENICS has suggested that the modification should be done in the GROUP 8 in GROUND.FOR, I don't know how to find the example in POLIS, could you give some information and instruction?

Thank you for your consideration and reply.

I think it should be PRNDTL(PHI)=ENUL/(DIFFUSION of PHI)

Thank you, Mr. Richard, I will try your suggestion in the simulation.
