Unable to use Gradient Limiter

      I am unable to use the Multidimensional gradient limiter with the density based solver (implicit). 
      Are there any conditions for using it? Thanks

      Bumping after 8 hours isn't going to do anything, especially overnight. 

      You're in the panel, what's the problem?

        The option to apply a limiter filter is greyed out. This doesn't happen for the standard and differentiable limiter

      Then it's likely not available for the solver settings.

      Any idea why? Nothing is mentioned about this in the fluent user manual

      No, but there are several models that aren't enabled in the Density Based Solver.
