Where are mesh adaption controls in ANSYS-Fluent 2021R1 ?

      Dear all,

      I am simulating a fluidized bed with transient multiphase, eulerian model. In order to have a well defined interfase region between the two phases I applied a refinement criterion in ANSYS-Fluent 2020R1 under the Adapt option:

      Adpation Controls => Refinement Criterion => Expression Editor=> Variables => Adaption => AdaptionSpaceGradient(Volumefraction)

      Adaption controls are in the Domain tab,

      and you'll want a cell register to refine and possibly one to coarsen if you're using dynamic adaption. Some of the options changed in the last couple of versions but I think the useful ones are still there. I'd suggest refining on a volume fraction range or gradient and coarsening on the same variable but at a different value(s).

      Yes. It works nicely when defining the Gradient of Volume Fraction in a new cell register and choosing it in the Refinement Criterion. There is no need for the AdaptionSpaceGradient variable.
      Thanks Rob.
