Recently I am checking on the aneurysm, and I found that:
T inletZpos = util::roundToInt(inletCenter) + 1; Box3D measureBox(lattice->getBoundingBox()); measureBox.z0 = measureBox.z1 = (plint)inletZpos; T inletPressure = DESCRIPTOR<T>::cs2 * (boundaryCondition.computeAverageDensity(measureBox) - 1.); T pressureDrop = inletPressure * util::sqr(dx / dt) * fluidDensity;
So the pressureDrop would be the pressure on the inlet I guess?
But on the page 11 of the paper ‘Palabos: Parallel Lattice Boltzmann Solver’, I found the description that:
The pressure drop between inlet and outlet
I’m kind of confused, isn’t that should be calculating pressure on the outlet and get subtraction?
