STEP 3: Observation Grids


Known incompatibilities between Poly3D and WEB Forms
Name and Shape of Observation Grid

You want to observation grid.
Obs. "Grid" Name :
Dimension :


Output Parameters --- Choose as many parameters as you want

Displacement vector
Principal stresses (magnitude & orientation) Stress tensor
Principal strains (magnitude & orientation) Strain tensor


Coordinate Systems

Endpt. Coord. Sys: used to specify grid endpoints during input
Obs. Pt. Coord. Sys: used to print obs. point position during output
Output Coord. Sys: determines x1, x2, x3 axes for stress tensor, strain tensor and displacement vector


Observation Grid Details

Begin End # of points
x1: vary only one row for an observation LINE
x2: vary two rows for an observation PLANE
x3: vary all three rows for an observation NETWORK
Within non-varying rows (xbeg = xend), enter location (xbeg & xend) and '1' for # of points
