I have simple model - 100 meters high building of simple geometry in the domain (1x3x0.6 km). I need mean pressures on the building facades. The model is working good until the elements on the facades (Mesh-Face sizing) are 1.5m. When I put them to be 1m the solver make just 10 steps and I have the message: Fatal overflow in linear solver
 . When I switch the turbulent model from RNG k-Epsilon to k-Omega it works.What can be the potential problems and solutions  ?Thank You in advance! Danijela |
