![]() When reopening the panel, it remains set on nglib. I clicked on the elmergrid option, applied but In Mesh>configure I saw that the preferred generator is set on nglibĪnd not elmergrid. Now I opened it in Elmer GUI, File>open, the design is completly destroyed, (I found out how to create it ), it opens well in Gmsh. This time ElmerGrid ran, I got the file with a beautiful boundary layer I didn't find how to create a boundary layer on the gmesh website, I am going to search more. I entered values for the boundary layer, Apply,Īnd it created my mesh but not the boundary layer. Then Mesh>Define>Size field>Boundary layer. In fact I have created points (with z=0), then lines on points, then an area on the lines, Your command must be good, but after opening ElmerGrid in a Terminal, typing ElmerGrid 14 2 ancre3 -autoclean I installed FreeCAD (on the File tab of the top boarder, only the Quit option appears, the software seems not to be finished) and LibreCAD (saves files in. I installed Grace for modeler but inside Grace I didn't find the possible extensions for saved files. But by loading into Netgen, an error message appears : « geo-file should start with algebraic 3D ». in2d files for 2D geometries, so I tried to load the. The geometry file could not be open in Elmer as well (a message appears, saying « Unable to mesh, no input data or mesh generator (please make sure that your input file suffix is in lower case) ». That should create you a file directory named name and the mesh files. msh (simply under Mesh-> Save in GMSH lets assume under name.msh) file and then create a ready made Elmer file using ElmerGrid (standalone outside ElmerGUI) ElmerGrid 14 2 name.msh -autoclean. But no one of the meshed files could be loaded in Elmer. the most easiest way, if you already have the GMSH mesh, is to export it to a. I installed Gmesh, which has a modeler, I draw my geometry, saved in. But if other field is evaluated, the previous is. My guess is that in your case is partially working, because gmsh creates and evaluates the field and use it as background due to the command 'BoundaryLayer Field 1'. I installed then Netgen, but I didn't find any modeler inside, as it seems to be only a mesher. The boundary layer field you are using can only be properly implemented as a mesh size indicator if used as background mesh. I tried then to create the geometry with Elmer modeler but on the Elmer modeler window no command appear but Editor with 2 tabs (one is Points with Idx, x, y, the other is Curve with out, in, pts, p1, p2, p3), and nothing happens by picking with the mouse. I have installed Elmer on my Ubuntu 12.04 configuration. I need to study a turbulent flow around a beam in 2D. > alexander.tismer at > _ĮMail: alexander.tismer at don't know which software to use to create a 2D geometry file or a meshed file that could be loaded to Elmer. > Please find attached a mesh cut of the final mesh. > Hi Alex - No if you change the definition of surfaces, you will indeed want to reparametrize the mesh vertices so that the transfinite algorithm (which works in parametric coordinates) can compute the new vertices correctly. But if I mesh some bounding surfaces using transfinite edges and surfaces there occurs very very flat elements in the final internal GRegion. > 5) mesh internal GRegion (orange elements) > 4) create elements in boundary layer (green elements) > I write a mesh operator that starts from a surface mesh and adds a boundary layer to it (according to this paper 2-R/abstract). Question again: is there any call to a reparametrization function of any bounding geometrical surface in the meshGRegion::operator() function? Because the surface mesh is moved, but the underlying geometrical surface definition doesn't change. Now I call the meshGRegion::operator() function. > GEdge::meshAttributes.typeTransfinite = 1 > GEdge::meshAttributes.nbPointsTransfinite = 10 ![]() Maybe an example: Assume there is a cube. > So my question: does the meshGRegion operator requests any mesh vertex reparametrization on its bounding faces of edges if using transfinite stuff?ĭoes the meshGRegion::operator() requests any mesh vertex reparametrization of its bounding faces OR edges if using transfinite stuff?
