<html><head><meta http-equiv="Content-Type" content="text/html charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi Salvatore,<div class=""><br class=""></div><div class="">What you are attempting to do can be achieved by adding a few custom calls to Grid_markRefineDerefine.F90. First, add a copy of Grid_markRefineDerefine.F90 to your Simulation setup directory that you will customize. Then add to it:</div><div class=""><br class=""></div><div class=""><font face="Monaco" class=""><span style="font-size: 12px;" class=""> call gr_enforceMaxRefine(lrefine_max-3) ! Enforce a max level everywhere that is 3 levels lower than lrefine_max</span></font></div><div class=""><font face="Monaco" class=""><span style="font-size: 12px;" class=""> </span></font></div><div class=""><div class=""><font face="Monaco" class=""><span style="font-size: 12px;" class=""> spec(1:3) = 0.0</span></font></div><div class=""><font face="Monaco" class=""><span style="font-size: 12px;" class=""> spec(4) = RADIUS_OF_REFINED_REGION</span></font></div><div class=""><font face="Monaco" class=""><span style="font-size: 12px;" class=""> call Grid_markRefineSpecialized(INRADIUS,4,spec,lrefine_max) ! Force refinement to lrefine_max within a sphere at center</span></font></div></div><div class=""><br class=""></div><div class="">The gre_lrefineMaxRedDoByLogR will force decrements as a function of radius which is not, if I understand, exactly what you want.</div><div class=""><br class=""></div><div class="">Hope this helps,</div><div class="">Sean</div><div class=""><br class=""></div><div class=""><br class=""><div class="">
