D3D Mesh Generator

D3D is a mesh generator capable to discretize in parallel (or sequentially) 3D domains into mixed meshes.

Developed by Daniel Rypl.

Basic Features:

• model topology: boundary representation
• model geometry: rational Bezier curves, surfaces and regions
• element size control: local, curvature-based, background tree based
• algorithm: quad/octree-based technique
• elements: linear and quadratic edges, triangles, quadrilaterals, tetrahedrons, pyramids, wedges and hexahedrons
• renumbering: nodal (Sloan)
• platforms: Unix, Linux, Windows
• message passing: MPI, Parmacs
• visualisation: Elixir X-Window graphic library by P. Krysl (Unix and Linux only)

Screen Shots:

The following screen shots present parallel discretization of a tunnel in a rock mass (two tubes - one completed including lining and one not yet fully excavated) on three slave processors (morpheus, zeus05 and zeus02) controlled by the master processor (cml).

• Wireframe model of the tunnel
• Wireframe model of the tunnel with highlighted regions of interest
• Parametric octree built separately on slave processors
• Parametric octree on selected regions
• Compatible parametric octree
• Compatible parametric octree on selected regions
• Discretization of curves
• Discretization of surfaces
• Shaded view of surface discretization
• Discretization of regions
• Completion of discretization
• Completed mesh on selected regions

Support:

Since 2001, D3D project is no longer maintained and supported.
