Cylinders and Pipes Construction¶
Cylinder¶
Simple Cylinder¶
To make a simple cylinder grid in python mode, the following data are required:
nbR : number of hexahedra on radial.
nbA : number of hexahedra along the perimeter of the cylinder.
nbH : number of hexahedra along the axis of the cylinder.
Use the function makeCyinderTop:
elts = doc.makeCylinderTop(nbR, nbA, nbH)
GUI command: Simple Cylinder
Uniform Cylinder¶
The following data are required:
origin : origin’s coordinates of the cylinder (select a vertex).
vx : the base of the cylinder (select a vector).
vz : the axis of the cylinder (select a vector).
rint : the radius of the hole in the cylinder .
rext : the radius of the cylinder.
angle : angle of the cylinder around the Z axis.
hauteur: the height of the cylinder.
nbR : number of hexahedra on radial.
nbA : number of hexahedra along the perimeter of the cylinder.
nbH : number of hexahedra along the axis of the cylinder.
Use the function makeCylinderUni to make a uniform cylinder:
elts = doc.makeCylinderUni(origin, vx, vz, rint, rext, angle, hauteur, nbR, nbA, nbH)
GUI command: Uniform Cylinder
Custom Cylinder¶
The following data are required:
origin : origin’s coordinates of the cylinder (select a vertex).
vx : the base of the cylinder (select a vector).
vz : the axis of the cylinder (select a vector).
tr : a list of radiuses in ascendant order.
ta : a list of angles in ascendant order.
th : a list of heights in ascendant order.
Use the function makeCylinder to make a custom cylinder:
elts = doc.makeCylinder(origin, vx, vz, tr, ta, th)
GUI command: Custom Cylinder
Operations on elts: Elements

Make Cylinders¶
To make two cylinders in T shape the following data are required for each cylinder:
orig : the origin of the cylinder (select a vertex).
vz : the axis of the cylinder (select a vector).
rext : the radius of the cylinder.
h : the height of the cylinder.
One of the two cylinders must be bigger than the other.
Use the function makeCylinders:
elts = doc.makeCylinders (orig1, vz1, rext1, h1, orig2, vz2, rext2, h2)
