<div dir="ltr">Luciano,<div> I think GRHydro inherited the atmosphere_mask from Whisky. In Whisky the atmosphere_mask was introduced to allow to set the RHS to zero for points within the atmosphere and to avoid to run Con2Prim in those points.</div><div>I do not think there is any advantage in using it and there should be no problem in setting the points to atmosphere locally without a mask (in Spritz, which comes from WhiskyMHD, we removed indeed the usage of masks).</div><div><br></div><div>Cheers,</div><div>Bruno</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Il giorno dom 10 dic 2023 alle ore 23:28 Luciano Combi <<a href="mailto:combi.luciano@gmail.com">combi.luciano@gmail.com</a>> ha scritto:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello people.<div><br></div><div>I've been using (a version of) GRHydro for a while and I was wondering if you know what motivated the use of an atmosphere mask.
