    <p>Hi,</p>
    <p>What I mean is that your simulation could have been running with
      2 or more refinements criteria at the same time and one criterion
      could be de-refining what the other is refining so at the end you
      don't see any refinement.  <br>
    </p>
    <p>As you said you need to have your own versions of
      Grid_markRefineDerefine.f90  and Grid_markRefineSpecialized  in
      your simulation folder and probably you have used the
      Grid_markRefineDerefine.f90 of one of the FLASH provided examples
      as a template.  This Grid_markRefineDerefine.f90  by default
      includes the  PARAMESH refinement criterion on these lines:</p>
    <p> do l = 1,gr_numRefineVars<br>
           iref = gr_refine_var(l)<br>
           ref_cut = gr_refine_cutoff(l)<br>
           deref_cut = gr_derefine_cutoff(l)<br>
           ref_filter = gr_refine_filter(l)<br>
           call gr_markRefineDerefine(iref,ref_cut,deref_cut,ref_filter)<br>
      end do<br>
    </p>
    <p>So, if you don't provide the refine_var on your flash.par, I
      think that this part of the code doesn't work, so you can debug
      your code by only including the <br>
    </p>
    <p>Grid_markRefineSpecialized refinement criterion.</p>
    <p>Guido,</p>

            <div>
              <p>Hi,</p>
              <p>I think this might caused by another refinement
                criteria been executed at the same time. So what your
                Grid_markRefineSpecilized refines is being de-refined by
                the default (or maybe another) FLASH refinement
                criterion. One way to check this is to run the
                simulation without the any parameter "refine_var_#" in
                your flash.par.</p>
              <p>Cheers,</p>
