The
Surface/Plane... menu item opens the
Plane Surface panel.
Plane Surface Panel
The
Plane Surface panel allows you to interactively create a planar surface that cuts through the domain. See Section
27.6 for details about the items below.
Controls
Options
contains options for defining the plane surface.
Aligned with Surface
enables the specification of a plane parallel to an existing surface.
Aligned with View Plane
enables the specification of a plane parallel to the current view in the active graphics window.
Point and Normal
enables the specification of a plane having a certain normal vector and passing through a specified point.
Bounded
enables the creation of a bounded parallelepiped, 3 of whose 4 corners are the 3 points that define the plane equation (or the 4 corners of the
Plane Tool).
Sample Points
enables the specification of a point density along the 2 directions (of the parallelepiped). This creates a uniformly distributed set of points on the plane. (This item is available only when the
Bounded option is enabled.)
Plane Tool
activates the plane tool. See Section
27.6.1 for details. This option is not available if you are using the
Aligned With Surface or
Aligned With View Plane option.
Sample Density
specifies the density of points when the
Sample Points option is enabled.
Edge 1, Edge 2
sets the point density along the two directions of the plane. (Edge 1 extends from point 0 to point 1, and edge 2 extends from point 1 to point 2.)
Select Points
activates the selection of points with the mouse. You can select endpoints by clicking on locations in the active window with the mouse-probe button. (See Section
28.3 for information about setting mouse button functions.)
Reset Points
resets the plane tool to its default position.
Surfaces
contains a list of currently defined surfaces. If you choose the
Aligned With Surface option, this will become a selectable list, and you can choose the surface with which you want the new plane surface to be aligned.
Points
contains boxes in which you can set the coordinates of the three points defining the planar surface.
x0, y0, z0
designates the coordinates of the first point.
x1, y1, z1
designates the coordinates of the second point.
x2, y2, z2
designates the coordinates of the third point.
Normal
contains boxes in which you can specify the components of the normal vector when the
Point And Normal option is enabled.
ix, iy, iz
designates the coordinates of the end point of the normal vector (the start point being 0, 0, 0).
New Surface Name
designates the name of the new surface The default is the concatenation of the surface type and an integer which is the new surface ID.
Create
creates the surface.
Manage...
opens the
Surfaces panel in which you can rename and delete surfaces and determine their sizes.
