1-year trial version for commercial users
Platform: UNIX (SUN Sparc, SGI, Linux)
Input: Native
Engineering Discipline:
-
medical imaging
Elements: Triangle, Quadrilateral
Surface Meshing: No
Tri/Tet Method: Advancing Front
-
Regular structures for circular and rectangular meshes.
Advancing front for irregular outlines.
Quad/Hex Method:
-
limited support for quads
Element Sizing Method:
-
Element size in regular meshes (circular and rectangular) is defined by global user structure definition.
Element size in irregular meshes is defined either manually from user-defined placement of boundary nodes, or automatic by specification of a fixed boundary-node distance.
Other Features: Refinement
-
The mesh program allows interactive local refinement, joining of nodes, and node displacement. Three scalar coefficients (absorption, scatter, refractive index) can be attached to each element, and modified interactively.
An integer value (group ID) can be attached to each element.
Meshes can be constructed from polygonal outline information of the outer surface and internal structures.
