Only a 2-D mesh has to be generated previously. Mesher does not need any definition of 3-D domain by commands. To ensure this property, it is important to use identical lines for adjacent contours. Another possibility is to generate twice the surface elements between the two domains.Īny kind of volume geometry can be meshed with that method provided it is topologically closed. The user must then delete himself surface elements. Now, if two contiguous domains are to be meshed, surface elements must be kept in order to be able to use a second time the common surface. Mesher shall be called upon as many times as there are domains to be meshed.Ĭommand replaces surface elements by volume elements. If the structure is made up of several three-dimensional domains, the GHS3D If second degree is necessary, use command. So, it is no use making second degree element in.
GHS3D cannot deal with interface nodes and does not generate any. The next points are worth to be mentioned: Similarly, the outer surface shall also be topologically closed, which means that two nodes shall in no way be superimposed.Īn access is provided in BACON through the. Structures consisting of two materials separated by a wall cannot be meshed altogether. PRT files are saved in a binary format, similar to an Alias wire model and an SDRC (Structural Dynamics Research Corporation) model. It contains surface and solid information for a single part. The object may contain enclosures and holes, but it must be all in one piece (only one 3-D domain according to the. A PRT file is a model part file saved in a three-dimensional model format used by Unigraphics, a 3D CAD program. GHS3D is distributed as an extension to the standard SAMCEF license.įrom a triangular surfacic mesh which represents the boundary of the object, the mesher generates and stores a mesh made up of tetrahedra.
#SIEMENS NX MESHING SOFTWARE#
The GHS3D software is an automatic tetrahedral mesher based on the Voronoi-Delaunay method which makes it possible to process any three-dimensional domain. In case of complex volumic structures, the GHS3D
