Value Filter

The Value filter available in the Contour panel allows you to specify threshold criteria for processing results only in a specific range. The Value filter discards any values not meeting the specified criteria. There are three possible modes to specify a criteria: greater than or equal to (>=), less than or equal to (<=), or a Range. The results will be displayed on entities (like nodes, elements, or systems) only when the value criteria is met. By default, no filter is applied (None). The Value filter is similar to that of an iso surface when processing results, with the difference being that no result is shown for the entities that do not meet the criteria (instead of removing those entities from display). The Value filter can be a useful tool for isolating the 'hotspot' areas. Using this filter along with the Count aggregation mode, allows you to count the number of layers meeting a certain criteria (for example, counting the number of plies exceeding a failure index).

The Value filter options (located in the middle of the panel) include:

Mode	Select an option from the drop-down menu: None (*Default setting) <= (less than or equal to) >= (greater than or equal to) Range
Value	Use the field(s) to specify a numerical value or range of values.

Mode

Select an option from the drop-down menu:

None (*Default setting)

<= (less than or equal to)

>= (greater than or equal to)

Range

Value

Use the field(s) to specify a numerical value or range of values.

Any entities (nodes/elements/parts/systems) that have values outside of the filter parameters will be displayed as gray in the graphics area.

The Value filter options can be used in conjunction with the Count and Layer filter , in order to determine which layers/plies are failing or exceeding certain threshold criteria.

The tables below illustrate how the various Value filter and Layer filter options work together:

counting_plies_chart1_hv

All layers are included in the count and other calculations (Max, Min, etc.).

counting_plies_chart2_hv

Only the layers which are less than or equal to 0.4 (the Value filter setting) are included in the count and other calculations (Max, Min, etc.).

counting_plies_chart3_hv

Only the layers which are greater than or equal to 0.4 (the Value filter setting) are included in the count and other calculations (Max, Min, etc.).

counting_plies_chart4_hv

Only layers 1, 3, and 5 (selected using the Layer filter) which are greater than or equal to 0.4 (the Value filter setting) and are included in the count and other calculations (Max, Min, etc.).
