<div dir="ltr"><div><div>Hi Christophe,<br><br>As a further follow up, using the latest version, the BL is now included in the extrusion and the physical group. However, when it is converted to OpenFOAM mesh, the BL is given is still given it's own patch. I suppose this is because <i>gmshToFoam</i> uses the <b>mesh partitions</b>, and <b>not the physical groups</b> to determine patches. However, what is more peculiar is that the patch only includes one side, even when I specify the extruded features in the BoundaryLayer Field. <br><br></div>In this simple case, I can alter the OF boundary file so that the BL is considered a part of the rest of the domain. However, issues arise when the BL is split over a number domains. So for example, if I alter the BoundaryLayer Field such that there is also a BL around the blades (see the attached geo file). The correct physical groups are specified, but when I use gmshToFoam, a patch is automatically defined as one side of the BL, which spreads out over two domains. <br><br><img src="cid:ii_jdfmafcl1_1617ba200d9e8c1c" height="404" width="561"><br><br><br>I suppose this is an issue with <i>gmshToFoam</i> and not with gmsh. I will post this same issue to OF mailing-list.<br><br></div>James<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Feb 9, 2018 at 4:47 PM, James Gross <span dir="ltr"><<a href="mailto:jgross0227@gmail.com" target="_blank">jgross0227@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Ubuntu 16.04.01<br></div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Feb 9, 2018 at 4:40 PM, <span dir="ltr"><<a href="mailto:cgeuzaine@uliege.be" target="_blank">cgeuzaine@uliege.be</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">Weird - which system?<br><br><div id="m_-1734495217448393707m_-8256448014435693314AppleMailSignature"><div><span style="background-color:rgba(255,255,255,0)">-- Sent from my phone</span></div></div><div><div class="m_-1734495217448393707h5"><div><br>On 9 Feb 2018, at 16:40, James Gross <<a href="mailto:jgross0227@gmail.com" target="_blank">jgross0227@gmail.com</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr"><div>Hi Christophe,<br><br></div><div>I pulled the latest version and installed it.
