Triangles will be recombined into quadrangles when possible. Data Recombine All: Applies a recombination algorithm to all surfaces.Tetrahedra will be recombined into prisms, hexahedra or pyramids if possible. Data Recombine 3D All introduced in version 0.20: Applies a recombination 3D-algorithm to all volumes.For more info, see section Element Recombination and for technical details see the Gmsh documentation. Data Recombination Algorithm introduced in version 0.20: The algorithm used for Data Recombine 3D All and also for Data Recombine All.Note: since Netgen can only create tetrahedral elements, this option is ignored for meshes whose Data Element Dimension is not 3D.
#Gmsh mesh width generator#
Data Optimize Netgen: Whether the mesh will be optimized using the 3D mesh generator Netgen to improve the quality of tetrahedral elements.To get a finer mesh at small corners or holes, this value can be increased for better resultsĮffect of Mesh Size From Curvature' left: set to 12, right: deactivated Data Mesh Size From Curvature introduced in version 0.20: The number of mesh elements per 2 π times the radius of the curvature.1st order meshes cannot be optimized because their element borders are linear an cannot be deformed. Elastic is an algorithm in which the mesh elements are treated as a collection of deformable viscoelastic solids. Introduced in version 0.20 Gmsh supports different optimization algorithms. The optimization is done by a deformation of the element borders. Data High Order Optimize: If and how meshes with Data Element Order = 2nd are optimized.So all surfaces of this region will form one physical group. For example a mesh of the same object region is internally tagged the same. They and are identified by their dimension and by a tag. Physical groups are collections of mesh entities (points, curves, surfaces and volumes). Data Groups Of Nodes: All nodes and not only the elements will be saved for each physical mesh group.The default 0.0 means that Gmsh's default of 1e-8 is used.
