anybody who have ever used the example phaseSeparation2d.cpp ?
I have just added a new geometry – a circle with a specific rho- at the lattice and the code does not work anymore. I have found out that the problem “segmentation fault” appears in the method sLattice.collideAndStream();
Any Ideas why this happens?
Which boundary conditions did you use? Bounce back would be my first try! Then, please check if the initial conditions are fine. In particular check, that they cause no big jumps in the density. Best Mathias
