Can Ansys Fluent be used to deal with bifurcation in Rayleigh-Benard problem?
I mean to compute critical Rayleigh numbers and the different flow cases like in the graph below?
Also, can we use nonuniform initial guess?
Yes. However the solution may be quite difficult to fully converge.
So how to use nonuniform initial guess?
Also, for bifurcation I could only get the marked solution , but the solution where there is two cells I could not catch.
Patch, you may need to set fluid zones or registers to set the velocities.
