1D Domains (Curves)

The 1D domain is a curve. optiSLang refers to curves as signal data, which includes all types of vector data that are assigned to an abscissa axis. Signal data can be visualized in optiSLang postprocessing that uses oSP3D as a backend.

2D and 3D Grids

Regular grids are domains where the connectivity is defined by the numbering of the nodes. While signals are 1D grids, there are also 2D grids (matrix data) and 3D grids (voxel data). Examples of 2D grids are performance maps or pixel-based images.

FEM Meshes

FEM meshes are unstructured grids in 3D.
