Results for Whole Surfaces
Results for whole surfaces
D3PLOT can also sum up results for contact surfaces, and the results can be viewed numerically in and . These values are the numerical sum of the relevant component for all segments in the surface.
When Ansys LS-DYNA writes contact surface results to the .CTF file it distinguishes between Surface A and B sides of each contact, therefore D3PLOT allows you to report results for contact surfaces as follows:
| A side | Results are computed from segments on the surface A side | ||||
| B side | Results are computed from segments on the surface B side | ||||
|
Surface as a whole where the summary results from A and B sides are within 5% by magnitude. (A and B sides should be equal in magnitude, and directional components opposite in sign.) |
Therefore the sign of the output of directional values is that of the surface B side. |
||||
| Surface as a whole where summary results from A and B surface sides differ by more than 5% by magnitude. (Typically the single-surface case, or "nodes to" types with no A surface segments.) | Whichever side has the greater value by magnitude, with no sign change applied. |
