Adaptivetime Stepping
I am simulating a transient fluidized bed using Eulerian model in ANSYS FLUENT. According to the FLUENT User's Guide, "Adaptive time stepping cannot be used with EulerEuler multiphase models."
but I saw several articles in which adaptivetime stepping algorithm has been used.
Using Constant time step would increase the computational cost since I have to use time step in order of E4; otherwise, backflow would be seen at pressureoutlet boundary.
I wonder if there is any way to use adaptivetime stepping in Eulerian modeling.
