Hi all,<br><br>(in the following, I only speak of surfacic elements such as quads and trias)<br><br>When introducing transpatch remeshing in GMSH, some elements that...<br>- have nodes lying on original CAD surface<br>- but an element surface "far" from original CAD surface<br>
...are likely to be generated between two CAD patches that may be tangential, but are globally not in the same plane.<br><br>These elements may be considered of "bad" quality because not representing correctly the CAD.<br>
<br>I would like to know if there is a way in GMSH to control the "surface deviation" criteria that would be for an element, the max distance between element surface and CAD surface.<br>A similar criteria could also be defined for edges: "edge deviation".<br>
<br>If this criteria can be evaluated in GMSH, is it possible to use it as a constrain when running GMSH remeshing?<br>Such a criteria that would tend to generate small elements, would compete with the criteria allowing to require for a homogeneous element size.<br>
<br>I thank you for any advices.<br>Have a good day.<br><br>Bests,<br><br>Pierre<br>
