2D Multi Cylinders

Problem definition

This test case consists in the simulation of the flow around two cylinders in tandem. With this test case we aimed to assess the hybrid method’s capability to simulate flows with more than one Eulerian sub-domain.

The configuration of the hybrid domain is presented below:
