Default boundary conditions
Posts: n/a
Hi I'm a post graduate student.. Can U pl tell me how can i implement the derivative boundary conditions.. for example the partial derivative of x-velocity along x-direction is equal to zero, or the partial derivative of pressure in any direction is zero...

thank you for ur reply

What do you mean by "implement"? Fluent will take care of the tangentional velocity magnitudes near the wall by the no-slip condition, and for fully developed flows, the derivative of the x-velocity in the x direction is zero, so you don't have to implement anything.

Sorry if I misunderstood your question!

Hi I'm a post graduate student.. Can U pl tell me how can i impose a boundary condition, second derivative of velocity(U) w.r.t x equal to zero.... How can I apply a linearly varying temperature along a wall..
