Compressible Fluid - Floating point exception - solution diverging -- CFD Online Discussion Forums

destroy Member Marcin Join Date: Jun 2016 Posts: 96 Rep Power: 9	Hello, Im performing FSI simulation (Fluent+Mechanical+System Coupling) and I tried to use a compressible density model for Water - to check whether it helps with stabilizing solution. However, I am getting a diverged solution. This does not happen when I use a constant density. I am using the same settings as default. I also tried to use a Density Exponent equal 1.0 - with the same unsuccesfull result. My settings are in attached image. In Fluent I am using an operating pressure (Physics->operating conditions) equal 101325 Pa, and Referrence pressure (set in Refference values) equal 0 Pa. What I am doing wrong? Regards
