Such a mesh point is automatically generated when a line which includes it on one extremity is meshed. If the point must be meshed on its own, for example when the point is the reference point of a string, it is done with the command: text/html 2016-03-30T13:23:04+00:00 Anonymous (anonymous@undisclosed.example.com) http://metafor.ltas.ulg.ac.be/dokuwiki/doc/user/geometry/mesh/1d?rev=1459344184&do=diff  1D Meshers (Curves) FIXME Mesh Elements versus Finite Elements: these two notions are different and should not be misunderstood. A mesh is made of geometric cells, the mesh elements. A finite element is a physical entity, which is supported by a mesh element. In Metafor, this is a two-steps method: first, the mesh is created, then the finite elements are applied to the mesh (this second step is done once the integration is started and programmed in the $s\in[0,1]$$n$${u(\xi) \; 0 \leq \xi \l… text/html 2021-12-17T13:02:05+00:00 Anonymous (anonymous@undisclosed.example.com) http://metafor.ltas.ulg.ac.be/dokuwiki/doc/user/geometry/mesh/2d?rev=1639746125&do=diff 2D Meshers (Surfaces) Metafor has a few integrated meshers, quite simple but usually capable of meshing parts that are not too complicated. However, 2D meshers require that the wire delimiting the domain has the right orientation.

For more complex geometries, it is necessary to divide it into hexaedra or use external meshers ($0 < \mbox{angle} < 360^\circ$$\mbox{angle} = 360^\circ$ text/html 2016-03-30T13:23:04+00:00 Anonymous (anonymous@undisclosed.example.com) http://metafor.ltas.ulg.ac.be/dokuwiki/doc/user/geometry/mesh/geniso?rev=1459344184&do=diff  Biomech GenIso Mesher This mesher is used to generate a 3D surface mesh from a 3D segmented image. Mono-material mesh The input is a 3D segmented binary image. It contains two values: voxels with a $0$ value are located outside of the object to mesh, voxels with a non-zero value are located inside.
