Thank you very much for your reply.
So does that mean I can’t get the linear velocity profile(which is predicted by the classical Fluid Dynamics theory) if I drag the wall past the water fluid and in the meantime, control the water’s temperature at 300K?
And if I want ro simulate the Couette flow, Should I turn off the thermostat?
Thank you all very much
The example is just a toy problem. In general, if you drag
a wall past a fluid you will heat it up. The thermostat prevents
