Post-processing Stress Results Using the Contour Panel

HyperView displays the following result data available in the result file:

•	Centroid data - the centroid is the integration point or the available value that has already been averaged by the solver (depending on the solver).

•	Integration points or Nodes (depending on the solver) - these results are "element bound", meaning that each is the contribution of the specific element to that node; therefore it is the corner data of that element.

The Use corner data option in the Contour panel allows you to display color bands by interpolating available corner results within each element. In addition, you can also use the Averaging method drop-down menu to select the result coordinate system to be used to contour the results.

•	Use corner data - controls if centroidal values or corner data is used for the visualization of values at an element.

•	Averaging method - controls in which way this data (centroidal or corner data) is visualized at the shared element nodes.

1.	From the Contour panel Result type drop-down menu , select the data type that should be used to calculate the contours (for example: Displacement (v), Stress (t), 1D stress, Energy (s), etc.). The available options will change depending on the currently loaded result file.

2.	Select the data component from the second drop-down menu below Result type .

contour_panel_result_type_drop_down_menu

The list of available components is based on the selected result type, for example:

Result type	Component options
Displacement (v)	Mag, X, Y, or Z
Stress (t)	vonMises, Signed vonMises, P1(major), P2(mid), P3(minor), MaxShear, Intensity, Pressure, In-plane P1(major), In-plane P2(minor), XX, YY, ZZ, XY, YZ, or ZX
1D stress	Multiple options are listed for various elements such as: CELAS, CROD, CBAR, CBEAM, etc.
Energy (s)	No component selection is necessary.

3.	If corner data is available, choose if an nodal or element value should be used by checking/unchecking the Use corner data option (see the element stress examples below).

Averaging: None

Averaging: Simple/Advanced

Use corner data off

One value per element: centroid value taken from result file.

post_prcssng_contour_pnl_cd_avg_off_ex1

One nodal value for all corresponding elements: averaged from each
centroid value.

post_prcssng_contour_pnl_cd_off_avg_adv_ex2

Use corner data on

IP value mapped to nearest node,
OR, the Nodal result from result file (whichever of the two is available): values are not averaged at node.

post_prcssng_contour_pnl_cd_off_avg_non_ex3

One nodal value for all corresponding elements: averaged using corresponding corner data values (either IP or nodal result from result file).

4.	For Selection, pick one or more entities from the model.

5.	For Resolved in, select the coordinate system that will be used to calculate the results.

-	If User System is selected, use the System input collector to select a system by ID.

6.	Use the Averaging method drop-down menu to select the averaging type of the element contribution at the shared element node (see the element stress examples below).

Only one element contoured: Averaging at nodes with values from that element.

contour_panel_use_corner_data_one_element_example

Values that are averaged at nodes have contributions from all of the attached elements.

contour_panel_use_corner_data_all_elements_example

7.	For Use variation (%), enter a percentage for the variation range.

8.	Activate the relevant check boxes for Display options, Legend threshold, and Result display control.

9.	Click Apply. The contour plot is displayed.

For Abaqus .odb files

The following results are available from *.odb files:

•	Centroid values

•	Integration point values: S-Stress component or S-Stress component IP (Integration Points), depending on the result type.

•	Nodal results: S-Stress component or S-Stress component IP (Integration Points), depending on the result type.

post_prcssng_contour_pnl_abaqus_odb_ex1

Averaging: None

Averaging: Simple/Advanced

Use corner data off

One value per element: centroid value taken from result file.

One nodal value for all corresponding elements: averaged from each centroid value.

Use corner data on

IP value mapped to nearest node
(S-Stress Components IP)

Nodal result from result file
(S-Stress Component)

In both cases, values are not averaged at node.

One nodal value for all corresponding elements averaged using corresponding corner data values:

IP value (S-Stress Component IP)

Nodal result (S-Stress Component) from the result file.

For *.op2 and *.h3d results

post_prcssng_contour_pnl_result_type_op2_h3d

SHELL elements Solver output default - values are available at the centroid:

•	Use corner data option is not available.

•	Averaging can be done on centroidal results (None, Simple, or Advanced).

When CORNER, BILIN, or CUBIC have been called in the solver - nodal results will be available in the result file for each element:

•	Use Corner Data option is available.

•	Corner data = nodal results are taken directly from the result file.

•	Averaging can be done in HyperView on the values taken from the result file.
