Grid-Minode Contributions

If you pick a minode in the 3D View, the grid point sources that contribute to the hazard at that minode will be plotted, scaled by how much they contribute. Theoretically, every grid point contributes to the hazard at a minode, but there is an accuracy threshold applied with a minimum probability to speed up the calculations. Increasing the accuracy will result in more contributing grid point sources.

The PPV-Exceedance Probability chart is also shown in this window. This is useful for understanding the effect of integrating the hazard of multiple minodes together. The probability of exceeding the design PPV increases depending on how many minodes are considered. You can use selection boxes to query any group of minodes you like.
