Pressure Coefficient to large when simulating on building

ivan.nikolaisson · May 11, 2018, 05:43

Hello

Im trying to simulate wind pressure on a building, and i want to obtain the pressure coefficient that is acting on the building. I have made my reference values correspond to my inlet, however, my pressure coefficient has the range from -3 to 2. In reality it should be between -1 and 1.

Any tips on where I could have gone wrong?

This is the contour plot of the building:

Hi Ivan,

I am suspecting the static free stream pressure you use to calculate the coefficient pressure is not correct.

Best regards,

Antoine

I’m doing the same topic like you. To compare with the wind tunnel test. Btw. I hope to have the group to discuss more ab this fields. I’m jumping into as a newbie
