Re: ComputeStress Function – Error ?
In NS equation, it is the pressure gradient that is to be found and not the pressure. Therefore, pressure is definded up to a constant, so that “”rho-1″” or “”rho”” should result in the same solution of NS equation. Using “”rho-1″” brings the pressure constant to zero, since usualy rho is set to be 1 + h^2. Do you see any differences in the result? Best Mathias
