Parameters
|
Type/Value
|
Description/Default
|
|
geom
|
xyz
|
Specifies Cartesian coordinates.
|
|
|
rtz
|
Specifies cylindrical coordinates. The center is at (0,0,0). Use a trans command to move the center. The minimum and maximum coordinates are the triplets: radius from the cylinder's axis, angle in the xy-plane measured from the x-axis and height along the z-axis.
Note that the rtz always results in a (partial) cylinder of points centered around the z axis. Use the rotateln command to orient the cylinder. For example, to center the cylinder around the y axis, specify the x axis as the line of rotation in the rotateln command.
|
|
|
rtp
|
Specifies spherical coordinates. The center is at (0,0,0). Use a trans command to move the center. The command minimum and maximum coordinates are the triplets: radius from the center of the sphere axis, angle in the zy-plane measured from the positive z-axis and the angle in the xy-plane measured from the positive x-axis (see section on mesh definitions).
|
|
ni, nj, nk
|
integers
|
Number of points to be created in each direction.
|
|
xmin, ymin, zmin
|
reals
|
Minimums for coordinates.
|
|
xmax, ymax, zmax
|
reals
|
Maximums for coordinates.
|
|
iiz, ijz, ikz
|
integers
|
if =0 then mins and maxs are used as cell centers
if =1 then mins and maxs are used as cell
vertices
|
|
iirat, ijrat, ikrat
|
integers
|
ratio zoning switches (0=off,1=on)
|
|
xrz, yrz, zrz
|
reals
|
Ratio zoning value - distance is multiplied by this value for each subsequent point.
|
|
line
|
line
|
This option implies xyz and will distribute n1 nodes from (xmin,ymin,zmin) to (xmax,ymax,zmax).
|
|
np
|
integer
|

rz / xyz / 5, 3, 10 / 0., 2., 0. / 5., 6., 2. / 1, 1, 1
This results in a set of 150 points, five across from x=0. to x=5., 3 deep from y=2. to y=6. and 10 high from z=0. to z=2.
rz / rtz / 4, 6, 11 / 0., 0., 0. / 3., 360., 10. / 1, 0, 1
This results in 264 points arranged around the z- axis. There are 3 rings of points at distances r=1., r=2. and r=3. from the z-axis. There are 11 sets of these three rings of points and heights z=0., z=1., z=2.,...,z=10. In each ring there are 6 points where each pair of points is separated by 60°; note that ijz=0 requests that points be placed at cell centers, hence the first point will be at 30° not at 0°. Corresponding to r=0, there will be 6 identical points at 11 intervals along the z-axis at heights z=0., z=1., z=2.,...z=10.
