Hi,
I am one of the students doing my final project on air flow against buildings. I am new to COMSOL and I had read all tutorials concerning the fluid flow but still many problems exist when simulation carried out. I have two blocks; block 1 is in block 2. I chose only one material (air) in block 2 (excluding block 1), and the flow is in laminar flow (2D). inlet and outlet also included in Block 2. I didn't change anything like equation, BC, initial value, etc...
After following the procedures, Meshing and Calculate, Problems like mu value for a material and the distribution shown is in one color (green) may appear in the system.
Is there anyone can assist me in this situation? ... I am using COMSOL 4.2.
Thanks

Hello Tiamwa,
A back-of-the-envelope calculation suggests that (assuming you used typical values for the material properties of air, the dimensions of buildings and velocity of the air flow at the inlet) the flow would not be laminar.
Of course there could be other problems with your set-up. Please consider posting your mph file to get more feedback from Forum users.
Best,
Jeff
