Hi,nI am working on spray cooling.I want to spray water in a compressible flow.The stagnation pressure is 4Mpa and static pressure is 0.696Mpa.I set operating pressure to zero and i enter 4Mpa and 0.696Mpa in pressure inlet boundary conditions.I enabled species transport.In materials for mixture template, i select ideal gas for density, mixing law for Cp and Sutherland Law for viscosity.I use pressure swirl atomizer.nAt the beginning of injection i recieve this error:# Divergence detected in AMG for pressure coupled: protective actions enabled!n# Divergence detected in AMG for pressure coupled, temporarily solve with BCGSTAB!nError: Divergence detected in AMG solver: pressure couplednWhat should I do?what is wrong?.RegardsnMiladn
