Good day to all,
I am a student of the Milan Polytechnic (energetic) and write in this forum because I also had problems regarding the turbulent vicosity ratio:
I am simulating a wind blade trunk with a profile du-97-w-300 characterized by "blunt trailing edge" and I created the mesh in icem by adding vortic generators on extradox (vortex generator vgs) in order to increase the stall angle of the shovel; the model of turbulence that I use is the spalart-allmaras considering the compress length.
as density imposed ideal gas and as viscosity use sutherland model and as equations all to the second order (use density-based approach).
performing a fmg (full multigrid initialization ) and launching simulation by "solution" I get the message in the image I attach (I also did the display of the contour of the viscosity ratio in the cells where this problem arises )
Can anyone help me?
nb: the problem is found after making the adapting on fluent in the region around the vgs
Thank you very much
