◆ residual_dirichlet()

Parameters **  P,
const Vector2 ***  x,
Vector2 ***  R 

Set the residual at Dirichlet locations

Compute the residual at Dirichlet locations and reset the residual to zero elsewhere.

Setting it to zero is necessary because we call DMDASNESSetFunctionLocal() with INSERT_VALUES.
