Internal Checks (Before Final Plots):
1) Run mesh error check2) Double check mesh refinement in regions of interest3) Check force/moment balance for loads and reactions4) Produce boundary conditions, translation plot, and stress plots for internal review5) If all is good start producing final materialsFinal Plots and Model Details:
1) Force and Moment Balancea. Use data table of results to produce load and reaction forces and moments
for loading and reaction nodesb. Include report of applied accelerations (where applicable)c. SHOW MASS SUMMATION TO ENSURE INERTIAL LOADS APPLIED
2) Model Detailsa. Produce plot demonstrating mesh size,b. Include material/thickness colors (w/ color key),c. Show load and boundary condition symbols (no need to include these on
any other plot).
3) Mesh Error Plota. Produce mesh error plot (focus on regions of interest)b. Discuss what parameters to use w/ Greg
4) Translation Plots,a. Produce total translation plotb. Legend thresholds auto-defined but colour contours user defined and
similar to those used for stress plots (see below)c. Contours on the deformed shape plot and show outline of underformed
shape
d. Provide individual component translation plots (TX, TY, TZ) for regionsof interest (where applicable)
5) Stress Plotsa. Provide VonMises plotsboth Top and Bottomb. Provide nodal stress labels in regions of maximum stressc. Use legend with reasonable number of levels and user defined colors
similar to the example image below.d. Linear Plot Special Considerations: Regions above ultimate should be
grey, regions above yield should be red, 80% of yield should be indicated
(yellow/orange type color)e. Non-Linear Plot Special Consideration: Regions above ultimate should be
red, 80% of ultimate should be indicated (yellow/orange), regions above
yield should be color indicated (Green??)

6) Margin of Safety < 0.2a. Create data table for all nodes with MS < 0.2 (note: believe this is
equivalent to querying nodes w/ stresses > 83% of allowable)
b. Table should include node number, location and stress (I can create theMS column with this data provided)c. Need to discuss this w/ Greg as I believe this is only applicable to theanalysis that require a non-linear run as the allowable is defined as
ultimate
Notes:For all plots identified above please provide additional detail views or different view
angles where required.Stress legend levels for contours should be selected to produce a relatively smooth
gradient in regions of interest (where possible)
