<div><div class="gmail_quote"><div><br></div><div>i recently read the Reisswig et al. 2012 paper and started trying to switch to cell-centered grid in order to be able to use the LSUThorns/Refluxing thorn. i am trying to simulate BH+torus systems and due to the size of the torus its hard to have it contained within a refinement level, so i thought that using a cell-centered grid in order to use refluxing might improve results..</div>
