How to Calculate the PPV

BLASTMAP^TM will calculate the PPV at every prediction point in the design. The PPV is calculated using the Wave Interference simulation.

To do so the Design must have prediction points and holes with explosives in them and have a Fire Time.

Note: If some or all of the holes don't have the above mentioned, BLASTMAP^TM will continue to calculate and finish at its own time with results that is not accurate.

Calculating the PPV

To calculate the PPV do the following:

Navigate to the Design Analysis menu.
Before you calculate the PPV you must add the correct values in the Wave Velocity field.
Left-Click on the Calculate PPV button.

BLASTMAP^TM will now calculate the PPV in the background. The progress of the calculation will be shown in the Status Bar.

The time it takes to complete the calculation will be dependent on the following factors:

The amount of prediction points in the design.
The amount of holes in the design.
The amount of decks in a hole.
The maximum fire time in the design.

Canceling the PPV calculation

Left-Click on the Cancel button on the Status Bar that is located to the right of the PPV calculation progress bar.
