changing coefficients of the equations with GROUND ?
 

Dear all,

Is it possible to change the coefficient of finite domain equation using the GROUND file ?

I see that INFORM facility enables the user to read the value of the coefficient of equation for each variable using APCO(Var_name), AECO(Var_name), AWCO(Var_name), etc. But when I try to change them in GROUND, it doesn't give any effect in the result. I have tried to change them in each section of GROUP 8 or GROUP 19, but no effect occured.

Thank's in advance.
