@Jmendezcarvajal@chenna1985@HiroNishikawa Your system is a very common occurrence in stokes saddle type problems. You need to handle the null space and the fact that your linear system in now saddle. You need projettion type solvers or block preconditioners and inf-sup elements
New paper out! “Acoustic Propagation/Refraction Through Diffuse Interface Models”. We propose a new method to simulate acoustic waves across diffuse interfaces — accurate, stable & multiphase-ready! 🌊
