line_test [recursionFlag]

Performs test along a single specified direction/position.
Use position and direction commands to change default.
Initial default: position(0,0,0), direction(0,0,1).
If recursion flag is set to TRUE, the intersection checks
will be performed recursively in the geometry tree.

Available Geant4 state(s) : Idle

Parameters

recursionFlag

type b

Omittable : default value = 0

grid_cells [X] [Y] [Z]

Define resolution of grid geometry as number of cells,
specifying them for each dimension, X, Y and Z.
Will be applied to grid_test and recursive_test commands.
Initial default values: X=100, Y=100, Z=100.

Available at all Geant4 states.

Parameters

X	type d	Omittable : current value is used as the default value.
Y	type d	Omittable : current value is used as the default value.
Z	type d	Omittable : current value is used as the default value.

grid_test [recursionFlag]

Start running the default grid test.
A grid of lines parallel to a cartesian axis is used;
By default, only direct daughters of the mother volumes are checked.
If recursion flag is set to TRUE, the intersection checks
will be performed recursively in the geometry tree.
NOTE: the recursion may take a very long time,
depending on the geometry complexity !

Available Geant4 state(s) : Idle

Parameters

recursionFlag

type b

Omittable : default value = 0

cylinder_geometry [nPhi] [nZ] [nRho]

Define details of the cylinder geometry, specifying:
nPhi - number of lines per Phi
nZ - number of Z points
nRho - number of Rho points
Will be applied to the cylinder_test command.
Initial default values: nPhi=90, nZ=50, nRho=50.

Available at all Geant4 states.

Parameters

nPhi	type d	Omittable : current value is used as the default value.
nZ	type d	Omittable : current value is used as the default value.
nRho	type d	Omittable : current value is used as the default value.

cylinder_scaleZ [fracZ]

Define the resolution of the cylinder geometry, specifying
the fraction scale for points along Z.
Initial default values: fracZ=0.8

Available at all Geant4 states.

Parameters

fracZ

type d

Omittable : default value = 0.8

cylinder_scaleRho [fracRho]

Define the resolution of the cylinder geometry, specifying
the fraction scale for points along Rho.
Initial default values: fracRho=0.8

Available at all Geant4 states.

Parameters

fracRho

type d

Omittable : default value = 0.8

cylinder_test [recursionFlag]

Start running the cylinder test.
A set of lines in a cylindrical pattern of gradually
increasing mesh size.
By default, only direct daughters of the mother volumes are checked.
If recursion flag is set to TRUE, the intersection checks
will be performed recursively in the geometry tree.
NOTE: the recursion may take a very long time,
depending on the geometry complexity !

Available Geant4 state(s) : Idle

Parameters

recursionFlag

type b

Omittable : default value = 0

recursion_start [initial_level]

Set the initial level in the geometry tree for recursion.
recursive_test will then start from the specified level.

Available at all Geant4 states.

Parameters

initial_level

type i

Omittable : default value = 0

recursion_depth [recursion_depth]

Set the depth in the geometry tree for recursion.
recursive_test will then stop after reached the specified depth.
By default, recursion will proceed for the whole depth.

Available at all Geant4 states.

Parameters

recursion_depth

type i

Omittable : default value = -1

run [recursionFlag]

Start running the default grid test.
Same as the grid_test command.
If recursion flag is set to TRUE, the intersection checks
will be performed recursively in the geometry tree.
NOTE: the recursion may take a very long time,
depending on the geometry complexity !

Available Geant4 state(s) : Idle

Parameters

recursionFlag

type b

Omittable : default value = 0

recursive_test
