Reply To: Weird Behaviour of Residuals in transient simulation

[ae22b001]

Hi, I tried turning it off, but the residuals continuously increase. Im using k-w sst with sutherland viscosity model. The udf is fine, I'm just varying outlet pressure. I tried checking the mass flux but it too continuously increases but that is probably because I'm varying outlet pressure.

Kindly help, the residuals only increase when istart changing outlet pressure, it is running fine if i do an unsteady simulation without changing any properties.
Should i use non-reflective boundary conditions?
