The subgrid approach affects both the display of geometric curvature and the display and printout of results<br />
quantities (displacements, stresses, etc.). However, when you use PowerGraphics in POST1 for derived<br />
quantities on solid elements, the maximum value on the plot and the maximum value in the printout may<br />
not agree. PowerGraphics displays do not average at geometric discontinuities. The printouts in PowerGraphics<br />
will, however, provide averaging information at geometric discontinuities if the models do not contain shell<br />
elements. Carefully inspect the data you obtain at geometric discontinuities.<br />
12.5.2. Printing and Plotting Node and Element Results<br />
You can list displacements, stresses, and strains at all node locations (both corner and midside nodes), using<br />
the PRNSOL command (Utility Menu> List> Results> Nodal Solution). For shell elements, you can list<br />
results and plot them at the top/bottom and middle layer locations. Likewise, these nodal values can be<br />
contoured for display purposes using the PLNSOL command (Utility Menu> Plot> Results> Contour Plot><br />
Nodal Solution). The number of facets per element edge that you specify determines contour resolutions.<br />
Note that results values for shell elements are displayed simultaneously for the top and bottom layers.<br />
When viewing nodal results using PowerGraphics (PRNSOL, PLNSOL, or the GUI Query function), you can<br />
average results in various ways. To choose how results are averaged, use the AVRES command (Main Menu><br />
General Postproc> Options for Outp or Utility Menu> List> Results> Options). (AVRES has no effect on<br />
the Degree of Freedom solution values (UX, UY, TEMP, etc.). You can average results at all boundaries (default),<br />
or at all boundaries except where real constant and/or material discontinuities exist. Results are not averaged<br />
at geometric discontinuities.<br />
Note<br />
In Full Graphics mode, it is possible to deselect an individual node, select all elements (including<br />
the element that contains that node), and then perform postprocessing calculations on those<br />
elements and have that unselected node not be considered in those calculations. However, if<br />
PowerGraphics is active postprocessing always displays based on selected elements.<br />
The minimum and maximum results values reported for your PowerGraphics plot will be based on the surface<br />
data. For stresses and strains, these values will usually be acceptable. Some thermal results, however, will<br />
have internal minimum or maximum values, and erroneous values will be reported. You may need to switch<br />
to full model graphics.<br />
Plotting and printing of element results are similar to that for the Full Model graphics method; you use the<br />
PLESOL or PRESOL command, or one of the following GUI paths:<br />
Command(s): PLESOL, PRESOL<br />
GUI: Main Menu> General Postproc> Plot Results> Contour Plot> Element Solu<br />
Utility Menu> Plot> Results> Contour Plot> Elem Solution<br />
Main Menu> General Postproc> List Results> Element Solution<br />
Utility Menu> List> Results> Element Solution<br />
The program unaverages nodal results and sorts them by element number. Averaging results does not affect<br />
element results plots. Results are for all nodal locations on the model surface. If you issued the /EFACET,1<br />
command, the results for the midside nodes are not listed.<br />
PowerGraphics does not support safety factor calculations.<br />
