DeViSoR is abbreviated for "Design and Visualization of Software Resource". The DeViSoRGrid application is part of that software family and is primarily used for the following tasks, so far in 2D only: * Geometry generation * Manual coarse mesh generation * Grid visualisation at all levels All of this can be done in a very confortable manner using a simple point and click interface like in common vector-based image processing software. Both the reliable FEAT file format and the new FEAST format with integrated parallelism are supported.
