ST7-R3.50.80.16 Removing Small-Area Plates using the TEXT Tab
This Webnote illustrates a method for detecting and removing plate elements with very small area. This is also applicable to brick elements with very small volume, and to beam elements with very small length. The small area elements can be a by-product of automeshing, such as when the geometry contains very small faces, or Surface Automesh parameters that are unable to accommodate the meshing of elements over small geometric features. Small elements can also be created inadvertently through manual meshing operations with tools such as Move to Absolute or Cut Elements. If these elements are too small, they can have an impact on the local stress field due to numerical round-off or ill-conditioning. Therefore, they should be removed from the mesh prior to analysis and the mesh repaired accordingly.
