COMSOL or Solidworks

Hello, I'm looking for a freelancer able to solve an open tank equipped with a Communicating vessels pipe under atmospheric pressure. Phase A: - Find out the maximum water flow rate in l/s (liter per second) that the actual 3D model can absorb. - Provide graphs as a proof of working system, as well as animation. If Phase A is successful, another job will be post for: Phase B (COMSOL only as I doubt that this can be done in Solidworks): - Build a schematic simplified 2D model to used as a based to build an abacus graph - Run iterative simulation with the most relevant parameters variable (Pipe's shape, Coef contraction create by thin wall orifice...) - Build an Abacus based on the result native file will have to be provided to be able to refine the simulation if necessary using Solidworks 2016, Comsol 5.3.
