  'elty' <set> 'be2'|'be2d'|'be3'|->
               'te4'|'te10' [<parameter>]
This keyword is used to assign a specific element type to a set of entities (see section Element Types in the appendix). The element name is composed of the following parts: The leading two letters define the shape (be: beam, tr: triangle, qu: quadrangle, he: hexahedra), then the number of nodes and at last an attribute describing the mathematical formulation or other features (c: axisymmetric, e: plain strain, s: plain stress, u: unstructured mesh, r: reduced integration, i: incompatible modes, f: fluid element for ccx). If the element type is omitted, the assignment is deleted. If all parameters are omitted, the actual assignments are posted:


will print only the sets with assigned elements. Multiple definitions are possible. For example,

elty all

deletes all element definitions. If the geometry was already meshed, the mesh will NOT be deleted. If the mesh command is executed again after new assignments has taken place, additional elements will be created.

elty all he20

assigns 20 node brick-elements to all bodies in the set all.

elty part1 he8

redefines that definition for all bodies in the set part1.

elty part2 tr6u

assigns 6 node unstructured triangle elements to all surfaces in set part2.

elty part2 tr6u 0.5

will do the same but specifies a mesh refinement factor of 0.5 (>1: coarser than the average boundary spacing, <1: denser )

elty part3 te10

assigns 10 node elements to all bodies in set part3. But this works only if NETGEN [4] is installed and the program ng_vol is accessible.

elty part3 te10 3.5

will do the same but specifies a target size for the elements. In this case the modified program ng_vol from the cgx-distribution must be available. Replace the original ng_vol in the NETGEN package and build it again.
