I want to specify the outlet boundary condition by setting zero pressure gradient.
Can we have the access to the variational form of the Navier Stokes equation? So that one can specify the required boundary condition directly?

Can we apply delP=0 boundary conditions in simvascular?
Also can we specify the dirchlet and the neuman conditions on the weak form of Navier Stokes?

Will the turbulent models like RANS and LES introduced soon?
