Mapdl.e(i='', j='', k='', l='', m='', n='', o='', p='', **kwargs)#

Defines an element by node connectivity.

Mechanical APDL Command: E

Parameters:

istr: Number of node assigned to first nodal position (node I). If I = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI).
jstr: Number assigned to second (node J) through eighth (node P) nodal position, if any.
kstr: Number assigned to second (node J) through eighth (node P) nodal position, if any.
lstr: Number assigned to second (node J) through eighth (node P) nodal position, if any.
mstr: Number assigned to second (node J) through eighth (node P) nodal position, if any.
nstr: Number assigned to second (node J) through eighth (node P) nodal position, if any.
ostr: Number assigned to second (node J) through eighth (node P) nodal position, if any.
pstr: Number assigned to second (node J) through eighth (node P) nodal position, if any.

Notes

Defines an element by its nodes and attribute values. You can specify up to eight nodes. You can add more nodes if needed ( emore ).

The number of nodes required and the order in which they are specified are described in Element Input numstr ) as generated. The current (or default) MAT, TYPE, REAL, SECNUM and ESYS attribute values are also assigned to the element.

When creating elements with more than eight nodes ( e followed by emore ), it may be necessary disable shape-checking ( shpp ) before issuing this command.

If a valid element type can be created without using additional nodes ( emore ), this command creates that element. emore then modifies the element to include the additional nodes. If shape-checking is active, it occurs before emore is issued. If the shape-checking limits are exceeded, therefore, element creation may fail before emore modifies the element into an acceptable shape.

Examples

Create a single SURF154 element.

>>> mapdl.prep7()
>>> mapdl.et(1, 'SURF154')
>>> mapdl.n(1, 0, 0, 0)
>>> mapdl.n(2, 1, 0, 0)
>>> mapdl.n(3, 1, 1, 0)
>>> mapdl.n(4, 0, 1, 0)
>>> mapdl.e(1, 2, 3, 4)
1

Create a single hexahedral SOLID185 element

>>> mapdl.et(2, 'SOLID185')
>>> mapdl.type(2)
>>> mapdl.n(5, 0, 0, 0)
>>> mapdl.n(6, 1, 0, 0)
>>> mapdl.n(7, 1, 1, 0)
>>> mapdl.n(8, 0, 1, 0)
>>> mapdl.n(9, 0, 0, 1)
>>> mapdl.n(10, 1, 0, 1)
>>> mapdl.n(11, 1, 1, 1)
>>> mapdl.n(12, 0, 1, 1)
>>> mapdl.e(5, 6, 7, 8, 9, 10, 11, 12)
