Meshing Facet

MESH200 Element Description

MESH200 is a "mesh-only" element, contributing nothing to the solution. This element can be used for the following types of operations:

Multistep meshing operations, such as extrusion, that require a lower dimensionality mesh be used for the creation of a higher dimensionality mesh
Line-meshing in 2-D or 3-D space with or without midside nodes,
Area-meshing or volume-meshing in 3-D space with triangles, quadrilaterals, tetrahedra, or bricks, with or without midside nodes.
Temporary storage of elements when the analysis physics has not yet been specified.

MESH200 may be used in conjunction with any other ANSYS element types. After it is no longer needed, it can be deleted (cleared), or can be left in place. Its presence will not affect solution results.

MESH200 elements can be changed into other element types using EMODIF.

MESH200 Input Data

The permissible geometry and node locations for this element are shown in Figure 200.1: "MESH200 Geometry". The element is defined by two to twenty nodes. It has no degrees of freedom, material properties, real constants, or loadings.

"MESH200 Input Summary" summarizes the element input. See Element Input in the Elements Reference for a general description of element input.

KEYOPT(1)

Element shape and number of nodes:

0 --: 2-D line with 2 nodes
1 --: 2-D line with 3 nodes
2 --: 3-D line with 2 nodes
3 --: 3-D line with 3 nodes
4 --: 3-D triangle with 3 nodes
5 --: 3-D triangle with 6 nodes
6 --: 3-D quadrilateral with 4 nodes
7 --: 3-D quadrilateral with 8 nodes
8 --: tetrahedron with 4 nodes
9 --: tetrahedron with 10 nodes
10 --: brick with 8 nodes
11 --: brick with 20 nodes

KEYOPT(2)

Element shape testing:

0 --: Shape testing is done (default)
1 --: No shape testing is done for this element

MESH200 Output Data

This element has no output data.

MESH200 Assumptions and Restrictions

When this element is a triangle or quadrilateral, it is shape-tested in the same manner as an equivalent "non-structural shell". When it is a tetrahedron or brick, it is shape-tested like a SOLID92, SOLID45, or SOLID95. This is so that meshing will work to create well-shaped elements. If KEYOPT(2) = 1, no shape testing is done for this element type.
MESH200 elements may not be active during result contour plotting (/POST1, PLNSOL, or PLESOL). The elements are automatically unselected during either operation.

MESH200 Product Restrictions

There are no product-specific restrictions for this element.
