Mesh3D Feature List (abbreviated)
• Import of ASCII or BINARY STL (Sterolithography) models for the geometry primitive
• STLGen to import NASTRAN bdf files and auto-convert select elements to STL triangles (STLGen can now be tested with our abreviated library of BDF neutral files) (see tutorial)
• Object modification, including stretching, translating and rotation of the incoming STL model
• One-click reversal of STL surface normals (to control the voxel flood fill projection)
• Unlimited merging of STL models, allows the buildup of complex geometry's
• Export the customized STL buildup model for future import
• Export of STL model to NASTRAN BDF CTRIA3 model
• Export of control surfaces to NASTRAN BDF CQUAD4 model
• Rhea-OV3D (ObjectView 3D) graphics engine for display
• Multiple edge and fill detection and creation methods
• Simple one-click control of the size of the mesh block
• Instant dialog feedback on the size of the hex mesh and number of bricks
• Voxel export selection, EDGE, FILL, BLOCK with bollean combinations of the latter, example BLOCK and NOT EDGE, allows control over dirty leaky STL files.
• Laplacian mesh smoothing algorithm with animated feedback to control the blend
• Animated edge detection and volume voxel filling for visual feedback and debugging
• Export to various neutral file formats, currently includes Harvard Thermal's TAS neutral file (NEU), Nastran bulk data file (BDF) and of course, Hyperion-TFS (TFM) geometry file
• Standard Rhea Tool pack, includes Rhea-PMA for creating AVI's
• NEW! Export of selected voxels using a special export (see tutorial)
• NEW! Set portions of the STL model as a SOLID, used to mesh dirty leaky STL model, preventing mesh bleeding

Hyperion-Mesh3D was developed to compliment the Hyperion-TFS CFD code. The development goal was to create a a rapid application development (RAD) tool that would allow the user to create a complicated 3D hexahedral mesh is seconds, having simple control and visual feedback. This has been achieved with Hyperion-Mesh3D. The usage is quite simple. Read in an industry-standard stereolithography (STL) model and a few button clicks, you have a hex mesh which either fills the STL or is the inverse of the space around the STL. Given the EDGE or FILL voxel detection, you then export various combinations to one of several industry standard neutral file formats.

Voxel Space
Mesh3D produces a structured hexagonal mesh by constructing a voxel space. The voxelization is converted to a general purpose hexahedral brick structured mesh. Mesh3D can apply an unlimited combination of STL primatives or full models.

Smoothing
Mesh3D applies Laplacian smoothing algorithms to refined the HEX mesh. The animation demonstrates the process. The user can control smoothing the mesh block faces if desired.
STLGen
NEW!
STLGen has been cut to a DLL and is incapsulated in Mesh3D. Now you can import an industry standard NASTRAN bulk data file and auto-convert select elements to STL triangles. STLGen also allows you to selectively clip graphical content during the conversion. In the following example, the STL was first exported as a BDF file, then imported to STLGen, then clipped graphically and then exported back as an STL.
