Block2D Command

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>

}
