Post-processing

There are following tools available:

Peak Finder

Peak Finder finds all peak zones based on the output results and presents them using a special plot and a summary table.

To open Peak Finder governing tool execute Post-Processing - Peak Finder - Add from the main menu:

Peak Finder menu

The following dialog window will be displayed:

Peak Finder

The peaks can be found for Fem Results (e.g. displacement, stresses, etc.) or Check results (except plate buckling). Select the load or the check results to use in the Result group box.

For the Load Results choose the Category and the Direction:

Peak Finder

The parameter and the direction should be defined for the Check Result

Peak Finder

In the Criteria filter it is possible to define the rule that determines the elements which are treated as peaks:

There are 3 different options for the criteria:

- The result is bigger/small than the defined value. For example, |Stress X| > 160MPa:

Peak Finder

If an Absolute option is ON it means that the absolute value of the result is used for the criteria. In the example above the compression stress is above -160 Mpa will pass the criteria.

- The number of elements - an amount of the elements with the Min/Max/Abs results.

Peak Finder

- The percent of elements - % of all the model elements with the Min/Max/Abs results. For example, select 1% of the elements with the maximum results on the Load Group:

Peak Finder

To preview the results press . The following table will be shown:

Peak Finder

Select the Load, define the selection and press Fill.

Export to component - export selected zones to the ncomponent.

It is possible to preview the peak zones on the model. Select the zones in the table and press the Plot.

Plot type - defines what values should be plotted on the model:

- Elemental values on zone elements - plot original values of the elements of the selected zones;

- Elemental values on zone elements + attached elements - plot original values of the elements of the selected zones and attached elements. For example when zones are very small (1 or 2 elements);

- Elemental values on selection - plot original values of all elements from the selection (ignoring elements from the zones).

Note: Labels will be displayed only for selected zones in the table. Show Only Welds option will be ignored.

- Absmax zone value on zone elements - plot all elements of the zone with the absmax value on the zone to keep each zone in a single color.

Show labels for each zone - put labels based on selected option near the element with a maximum value of the zone:

- None - do not show any labels;

- Id - id of the zone (e.g. "z1");

- Value - only absmax value over the element of the zone;

- Id and Value - zone id and zone absmax value (e.g. "z.1=123456");

Zone label font size - defines the label font size for all labels of the plot.

The Show Only Welds options are designed for a large model with a small mesh. The plot is shown only with the peaks and the welds elements. Show Only Welds = ON:

Peak Finder

Show Only Welds = OFF:

Peak Finder

Note: Weld elements are taken from the Weld Finder Tool. If no welds are recognized the elements with free edges will be displayed.

Governing Loads

Governing Loads - finds the critical (governing) loads from a large group of load combinations.

To open the Governing Loads tool execute Post-Processing - Governing Loads - Add from the main menu:

Governing_loads_menu

The following dialog will be displayed:

Governing_loads

The Governing Loads can be found for the Fem Results (e.g. displacement, stresses, etc.) or the Check results. Select the load or the check results to use in the Result group box.

Note: Governing load can be calculated only on Load Group. Besides, only checks with Load Calculation = All Loads are displayed in the filter.

For the Load Results choose Category and Direction:

Governing_loads

The governing loads can be found only for the checks with the Load Calculation option = All Loads. In the filter only supported checks are shown. the Parameter and direction should be defined for the Check Result:

Governing_loads

In the Criteria filter it is possible to define the rule that determines elements for which the governing loads hava to be found:

There are 3 different option for the criteria:

  - Result is bigger/small than a defined value. For example, |Stress X| > 160MPa:

Governing_loads

  If the Absolute option is ON it means that the absolute value of the result is used for the criteria. In the example above, the compression stress above -160Mpa will pass the criteria.

  - Number of elements - the amount of the elements with Min/Max/Abs results.

Governing_loads

  - Percent of elements - % of all the model elements with Min/Max/Abs results. For example, select 1% of the elements with the maximum results on the Load Group:

Governing_loads

In table 4 elements are displayed. All results are positive (tension) and the compression is skipped because the LG Parameter is set to Max:

Governing_loads

To find the governing loads for the compression stresses only, set the LG Parameter to Min, and take into account both to Abs.

In the Options group box select the Load Group, Selection and Table Type.

Governing_loads

By default, the full model is used, but if is required to skip some elements to modify the selection using the Selector.

The Summary Table (over loads):

Governing_loads

In total 24 elements passed the criteria |Stress X| > 160MPa. For each load the following information is shown:

Element Count - how many elements are governing for that load;

Element Id - the element with the worst value caused by the load;

Abs Value - the worst (Min/Max/Abs) value.

Expand Table - the detailed table that presents the results over the elements:

Governing_loads

- plot elements of selected governing loads in colors and put labels of load description. In addition it is possible to include labels of Peak values for each load by selecting necessary Show Max Label Type:

- None - only load description labels are shown;

- For each load - put one label with Peak Value at the center of corresponding elements;

- For each load zone - when load generates peaks at different locations of the model, label will be show for each connected zone with max value on each zone.

Note: Plotting is enable only for summary table type.

Governing_loads

- create the Load Group from all peak loads in the table and add it to the respective Job.

Freebodies

Freebody - calculates a balanced set of forces/moments on a chosen part of a model. It is possible to retrieve internal/external loads to be used for substructure modeling or find contact/connector forces by manipulating with a custom selection of nodes/elements.

To open Freebody tool execute Post-Processing - Freebodies - Add from the main menu:

Freebody

The following dialog window will be displayed:

Freebody

Settings:

- Loads - selected necessary loads to calculate freebody on. Each load is calculated separately per each selection.

- Csys - coordinate system used to rotate forces/moments;

- Mode - calculate origin at selected nodes (for each created selection separately) or take origin of selected Csys (same for all selections);

- Display type:

      Short (nodal sums + total) - display the summarized result on each node from attached elements:

Freebody

      Detailed (corner results + total) - detailed result on all nodes from selection and each attached element to respective node:

Freebody

      Total (overall summation) - summarized values on all nodes of respective selection pair:

Freebody

- display only rows where all forces/moments on each node satisfy set condition (e.g. skip small values).

Note: Condition is ignored for summation rows.

Selections:

List of selection pairs (elements and nodes) to calculate freebody on. The result is calculated on each selection pair separately.

Freebody

- add new selection pair:

Freebody

Title - selection pair title. If not set - short description of elemental selection will be used by default.

Pick elements using Load Selector Control.

Nodal method:

      - All nodes from elements - pick all nodes from selected elements automatically;

      - Free-edge nodes from elements - find all nodes free-edges of selected elements. Useful with selections that include holes;

      - Custom selection - manually pick necessary nodes using Load Selector Control.

Show nodes - displays nodes on a model that will be used in calculations:

Freebody

- edit selected selection pair;

- copy selected selection pairs;

- remove selected selection pairs;

Press Fill Table to display results.
