hi, everyone

I defined two user scalars(c1 and c2), and the source term of two scalars are w1 and w2.

w1=w1(c1, c2)
w2=w2(c1, c2)

First, I set the the source term in the explicit form(the value of w1, w2 are at time step n), but the result is divergence.

So I want to set the source term in the implicit form(the value of w1, w2 are at time step n+1).


How to do this?

thanks!
