The block3D command generates three-dimensional meshes of eight-node brick solid element.
block3d $nx $ny $nz $e1 $n1 element elementArgs {
1 $x1 $y1 $z1
2 $x2 $y2 $z2
3 $x3 $y3 $z3
4 $x4 $y4 $z4
5 $x5 $y5 $z5
6 $x6 $y6 $z6
7 $x7 $y7 $z7
8 $x8 $y8 $z8
<9> <$x9> <$y9> <$z9>
...
<27> <$x27> <$y27> <$z27>
}
$nx $ny $nz |
number of elements in the local x,y and z-direction of the block |
$e1 |
starting element number for generation |
$n1 |
starting node number for generation |
element |
define which brick element (Bbar Brick Element, Standard Brick Element) is being used |
elementArgs |
list of data parameters for element being used. This list may include, but is not limited to, a $matTag number |
{$x1, .... $x27} {$y1, .... $y27} {$z1, .... $z27} |
coordinates of the block elements in three dimensions. |
NOTE: this command only recognizes variable substitutions when the command
arguments are placed in quotes rather than braces
Only the first eight nodes (1-8) are required. Nodes 9-27 are used to generate curved meshes. The user may specify any combination of nodes 9-27, omitting some of them if desired.
