Facility Vulnerability with VISAC

Edit Grid Parameters

To define your own grids or edit existing grids, launch the Contour viewer using the VISAC menu option Facility/Grids/Edit Grid Parameters. In the Grid Select box, the user can select one of the grids listed and then click the "edit" to change the parameters of that grid. The user can also click on the "add" button to start defining a new grid.

Grid parameters have four main parts:

• Grid basics - grid name.
• Grid geomtry - extent and number of points in each dimension. Users can type in the values for the extents or use the 2D Triple View Slicer.
• Explosive parameters - charge type and weight.
• Calculation parameters - what type of QuickBlast mode to use, limit the calculation to interior or exterior points.

The blast points can be calculated with each grid definition or calculation can be put off until all the grids are defined.
