Hello
I want to implement power "m" in a function in openFoam 1.6 and I have an error message that said I have to define m as a "double" while now I have "double&". "m" definition is as follows:

scalar x0=0.5;
double x=centres[celli].x();
double m=pow(x-x0,10)+1;
scalar y0=0.1;
scalar a=0.5;
double b=1-pow((x-x0)/a,2);


what is the bug of my code?

hi friend
i guess problem where u subtract an scalar value from double!
so define x0 as double instead of scalar maybe it works
