Creating Plastered Cells

es-ice provides facilities for manually changing cell shapes in order to capture certain features in the geometry.

Consider the intersection between the cylinder wall and dome after mapping. This intersection region could be a nearly-flat surface in some cases, as depicted in Figure 21-1.

The hexahedral cell in the corner contain faces meeting at an angle of 180 degrees. This area needs to be modified by removing these cells and replacing them with prisms. This will result in a better mesh, shown in Figure 21-2.

The above operation may be performed by removing the offending cells from the dome, creating an edge, and ‘plastering’ the interior of the edge. This new edge should then be cleared and Cset 1 updated. The required steps are summarised in Figure 21-3 below.
