Bound computation

All options refer to the surfaces of circular shape.

Computation bound by one point

Assigned a grid of centers, examine all the eligible surfaces passing through a point assigned by the user. To use the bound computation proceeds as follows:

Computation bound by two points

It is not necessary to assign a grid of centers, the computation takes place automatically and examine all eligible surfaces passing through the two points assigned by the user and tangent to a straight line of variable inclination between 0 ° and 90 ° in steps of 1 °. To use the bound computation proceeds as follows:

Computation bound by three points

It is not necessary to assign a grid of centers, the computation takes place automatically and examine all eligible surfaces passing through the three points assigned by the user. To use the bound computation proceeds as follows:

Computation bound: tangent to a straight line

Assigned a grid of centers and a straight line is studied all eligible surfaces tangent to the line defined by the user having the center on the given grid. To use this type of bound computation proceeds as follows:

Downstream interval

Examines all surfaces whose intersection with the slope fall into two segments, one downstream and one upstream. To use this type of bound computation proceeds as follows:

In the example, the value of the maximum angle aperture is equal to 80° while the step of the angular variation is equal to approximately 10°;

in yellow are the tangent lines that bind the failure circles calculated by the program

The program does not perform the computation if it doesn't find a surface compatible with the assignments made.

Bound on a series of points

Examines a series of bound surfaces on a number of points. Insert the bounds in the appropriate grid.
