Two-Phase Flow, Phase Field multi physics with compressible flow

Please login with a confirmed email address before reporting spam

I am trying to simulate a liquid piston air compressor - water are entering a vessel full of air and therefor the air start to compress (the air pressure rises), with the Two-Phase Flow, Phase Field multi physics, and have a problem with defining the problem as compressible flow in the laminar flow physics model. As the "Nonlinear solver did not converge." Can Phase Field multi physics work with compressible flow? and how do i define only the air as compressible as the water are not?

Hi Or Yogev, I have also encountered similar issues. Did you try changing the advanced settings to use the conservative form? Send me your email.
