APDL Command: BLC4#

rectangle starting at (0.25, 0.25)

Create a block with dimensions 1 x 4 x 9
with one corner of
the block at (0, 0)
of the current working plane.
This method returns the volume number.

mapdl.vplot(show_lines=True)
APDL Command: BLC5#
Create a rectangular area or block volume by center and corner points.
This differs from BLC4 since this describes the center rather than the corner points.
Create a square centered at (0, 0)
with a width of 0.5 and a
height of 0.5
mapdl.clear()
mapdl.prep7()
anum1 = mapdl.blc5(width=0.5, height=0.5)

with the cetner at
(0, 0)
of the current working plane.
This method returns the volume number.

APDL Command: BLOCK#
Create a block volume based on working plane coordinates with the
size (1 x 2 x 3)

APDL Command: CON4#
Create a conical volume anywhere on the working plane.
Create a cone with a bottom radius of 3 and a height of 10.

vnum = mapdl.con4(rad1=3, rad2=0, depth=10)
mapdl.vplot(show_lines=False, quality=6, show_bounds=True)
APDL Command: CONE#
Create a conical volume centered about the working plane origin.
Create a quarter cone with a bottom radius of 3, top radius of 1 and
a height of 10 centered at (0, 0)
.

mapdl.prep7()
vnum = mapdl.cone(rbot=5, rtop=1, z1=0, z2=10, theta1=180, theta2=90)
mapdl.vplot(show_lines=False, quality=6, show_bounds=True)
APDL Command: CYL4#
Creates a circular area or cylindrical volume anywhere on the working plane.
Create a half arc centered at the origin with an outer radius of 2 and an inner radius of 1.
Note that the depth
keyword argument is unset, which will
generate an area rather than a volume. Setting depth to a value
greater than 0 will generate a volume.
mapdl.clear()
mapdl.prep7()
anum = mapdl.cyl4(xcenter=0, ycenter=0, rad1=1, theta1=0, rad2=2, theta2=180)
mapdl.aplot(show_lines=True, line_width=5, show_bounds=True, cpos="xy")
Create a volumetric half arc centered at the origin with an outer radius of 2 and an inner radius of 1, and a thickness of 0.55.
mapdl.clear()
mapdl.prep7()
anum = mapdl.cyl4(
xcenter=0, ycenter=0, rad1=1, theta1=0, rad2=2, theta2=180, depth=0.55
)
