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 WRITE and XY_DATA . 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.)

Directional (eg X force) (B side - A side) * 0.5
Magnitude values (A side + B side) * 0.5

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.
