ABOUT GriddleGriddle is a fully interactive, general-purpose mesh generation plug-in for the Rhinoceros 5.0 3D CAD software. Griddle can be used to remesh Rhino surface meshes to comply with precise size specifications and type (triangle or quad-dominant). Surface meshes can then be used as boundaries for Griddle’s volume mesher, which produces high-quality tetrahedral or hex-dominant meshes. The volume meshes are ready for import into most engineering analysis packages, including FLAC3D and 3DEC.
FEATURES
RHINOCEROS 5.0 PLUG-IN• Griddle extends, while leveraging, the
power of Rhino software• Rhino (sold separately*) can create, edit,
analyze, document, render, animate, and translate curves, surfaces, solids, point clouds, and polygon meshes
• Built-in Mesh Repair Wizard to ensure good-quality meshes for volume meshing
• Affordable, requiring standard hardware, short learning curve, low purchase price with no maintenance fees
• Compatible with most design, drafting, CAM, engineering, analysis, rendering, animation, and illustration software
• Powerful, accurate, and free-form• Customize, parameterize, and automate
Rhino and Griddle using powerful Visual Basic and Python scripting
GRIDDLE SURFACE MESH INTERSECTOR• Creates a conformal (node-to-node)
triangular mesh from any number of selected, intersecting meshes
• Requires only a single tolerance input
GRIDDLE SURFACE REMESHER• Remesh any Rhino mesh• Output meshes can be triangle, quad-
dominant (triangles and quadrilaterals), or all quadrilaterals
• Specify the minimum and maximum edge lengths as well as the ridge angle which controls the level of mesh detail
• Automatically delete or retain your original mesh
• Additional edge size controls include local mesh size overrides
• Specify hard edges that will be preserved in a mesh during the remeshing process

Brand new, powerful, easy-to-use meshing software for complex simulations. Model generation
has never been easier!
Griddle can handle the most complex geometries with multiple volumes and surfaces, including floating surfaces

GRIDDLE VOLUME MESHER• Creates a tetrahedral or a hexahedral-
dominant mesh using selected surface meshes as boundaries
• Surface meshes can be composed of triangles or a mix of quadrilaterals and triangles
• “Floating” surface meshes inside a volume (e.g., discontinuous geological joints) can be included as “hard faces” in the final volume mesh
BLOCKRANGER• BlockRanger is a Rhino plug-in included
free with Griddle• After partitioning your model into
tetrahedral-, prism-, and hexahedral shaped solids using Rhino, BlockRanger will automatically mesh these volumes with high-quality, mapped, all hexahedral elements.

BENEFITS• General-purpose interactive mesh
generator with applications from fluids and geomechanics to structures and biomedical
• Easy to learn and to use. If you know Rhino, you already know how to use Griddle.
• Griddle and BlockRanger volume meshes can be imported directly into FLAC3D and 3DEC, and into many other numerical modeling software packages
• Mesh discontinuities are automatically defined as joints in 3DEC and can be easily specified as interfaces in FLAC3D
TRY THE DEMOItasca is pleased to offer free demo versions of all software for download. There is no restriction to the length of time you can use the demos, but some mesh size restrictions apply.
