2D modelers
Posted: 18 Nov 2012, 12:23
Hello,
I don't know which software to use to create a 2D geometry file or a meshed file that could be loaded to Elmer.
I guess it should be wether a .grd or a .in2d file. Thanks for the help you can bring to me.
Following lines are what I tried to do :
I need to study a turbulent flow around a beam in 2D. I have installed Elmer on my Ubuntu 12.04 configuration. 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 installed then Netgen, but I didn't find any modeler inside, as it seems to be only a mesher. I installed Gmesh, which has a modeler, I draw my geometry, saved in .geo file, (also meshed it and saved in .geo, .bdf, .diff, .inp, .ir3, .mail, .mesh, .med, .msh, .opt, .p3d, .ply2, .stl, .unv, .vtk, .wrl). But no one of the meshed files could be loaded in Elmer. 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) ». I saw then that Elmer likes .grd or .in2d files for 2D geometries, so I tried to load the .geo geometry file to Netgen to create a .in2d file. But by loading into Netgen, an error message appears : « geo-file should start with algebraic 3D ».
I installed Grace for modeler but inside Grace I didn't find the possible extensions for saved files. 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 .dxf, .cxf, .lff).
I don't know which software to use to create a 2D geometry file or a meshed file that could be loaded to Elmer.
