<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Dear All,<br><br>I generate a set of surfaces (patches) which together define a closed shell and then use a surface loop to define the closed shell.<br><br>Meshing this setup creates a separate mesh for each surface (patch). How can I make Gmsh:<br>a) `glue' all these `patches' together and treat them as a single surface?<br>b) following a), create a single mesh covering the entire closed shell?. Currently, since Gmsh treats each patch seperately and does not `see' the full shell if I want to refine the mesh I must set the element size to be smaller then the sides of the patches, but it should relate to the sides of the entire shell.<br><br>Cheers and thanks,<br>Mike.</td></tr></table><br>
