Fixing values in a poisson eqn

2007-08-02 Thread Ben Tay
Hi, I am trying to solve a pressure poisson eqn resulting from the NS eqn. How can I fixed the pressure at some nodes while solving the poisson eqn? I tried to make the coefficient of the diagonal location of the node very big e.g. 1e100. I also use call
