Plate Contours Compared to Spreadsheet Values
After solution in RISA-3D, you can use Results View Settings to view the Plate Contours graphically on your model.
Many times, these contour values will not exactly match the values reported in the Plate Forces/Stresses spreadsheets.
This is because the contour maps are created using a smoothing algorithm that connects the spreadsheet value (this is the true analysis value, taken at the center of each plate with the values of the plates around it to create the contour).
You can increase the accuracy of your contours by meshing your plates into smaller plates, but for design purposes, we still generally recommend that you use the spreadsheet values.
