The block2D command generates meshes of quadrilateral elements in two or three dimensions. In three dimensions, a two-dimensional surface appropriate for shell analysis is generated.

block2d $nx $ny $e1 $n1 element (element arguments) {
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>
}

$nx number of elements in the local x directions of the block
$ny number of elements in the local y directions of the block
