Type

HyperMesh Tcl Query Command

Description

Returns coordinate data defining WAD grid points. The data will be returned as a list of one string, two integers, and three doubles. The string defines whether the point is child, middle or adult. The two integers are the row and column indices of the grid point. The three doubles are the X, Y, and Z coordinates of the grid point. For example:
Child -6 3 1.45816988887E+003 -600 8.59794186814E+002 Middle -1 6 1.75816988887E+003 -100 9.73484336137E+002 Adult -5 9 2.05816988887E+003 -500 1.03367256770E+003

Inputs

wad_child_min
The WAD line where child impact points begin.
wad_child_max
The WAD line where child impact points end.
wad_adult_min
The WAD line where adult impact points begin.
wad_adult_max
The WAD line where adult impact points end.
side_tolerance
GTR - No impact points are found within this distance of the side reference lines.
EuroNCAP, CNCAP - Impact points found within this distance will be deactivated.
protocol_method
The method to use for measuring the side_tolerance distance.
0 - Euro NCAP (default if not specified)
1 - Homologation
2 - ECER
3 - UN-R127 for corners, Euro NCAP elsewhere
4 - CNCAP
protocol_version
Used for Euro NCAP protocol, 7.0 (default if not specified), 8.0 or 8.2.
grid_spacing
The spacing between the impact points, default 100.0.
EuroNCAP, CNCAP - The grid spacing between the two nearest impact points in the same row or column.
GTR - The spacing between headform points on a wadline.
vertical_spacing
For GTR, it is the spacing between 2 wadlines on which impact points need to be created, default 100.0.

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
