Results Section

  • Used to specify the results that needs to be translated or filtered by VMoveCAE.

  • This is an optional section.

  • If not specified, VMoveCAE exports all the results with the default settings into CAX file.

  • Each data line should contain the name of the result that needs to be translated or filtered.

  • Alternately, users can specify the source result name in the native CAE solver instead of using VCollab result name.

  • Wildcard character * is supported.

  • Unlike Parts and Steps, the Results section provides the functionality to allow the users to export the same result multiple times into CAX files each time with different settings.

  • Usage Example:

    * RESULTS
    
    - Displacement, SOURCE=U
    - NT
    - S, DERIVED=VON_MISES, THRESHOLD=75
    - Elemental Stress, SOURCE=S, POSITION=E
    

Section Attributes

  • UNSPECIFIED: Allows user to specify Whether to translate or filter the unspecified parts. It’s default value is false, i.e. unspecified results are not exported into CAX file.

Data Attributes

  • TRANSLATE: Translates the specified results. This is the default behavior.

  • FILTER: Filters the result from Cax output.

  • SOURCE: Name of the variable in the source CAE solver. Supported source values are: :ABAQUS_ODB: U, S, E, PE, PEEQ, LE, THE, NT, NT11, NT12, AC_YIELD, VEEQ, CPRES, CNORMF, CSHEAR1, CSHEAR2, CSHEARF, COPEN, CSLIP1, CSLIP2

  • POSITION:

    • Instructs VMoveCAE whether to export nodal (N) or elemental (E) values.

    • Nodal values are exported by default.

    • For elemental results and for results that are defined at integration points, the nodal averaged values are exported.

  • MAPTYPE: Determines how the nodal values are computed from element/integration point values. Supported values:

    • GEOAVG: Nodal values are computed by using geometry weights ( area/volume) for the connected elements. This is the default value.

    • AVG: Nodal values are computed by averaging the connected element values.

    • MAX: Nodal values are taken as the maximum of the connected element values.

    • MIN: Nodal values are taken as the maximum of the connected element values.

  • SECTION: Defines the sections to extract when values are defined for multiple sections.

    • Shell, beam and membrane elements contain multiple values per element defined at different sections.

    • User can define the sections for which the values that needs to be extracted using this option.

    • Supported values:

      • TOP: Top section values.

      • BOTTOM: Bottom section values.

      • MAX: Maximum of all sections.

      • MIN: Maximum of all sections.

      • AVG: Average of all sections.

    • Default value: “TOP, BOTTOM”

  • DERIVED: Derived component that needs to be extracted.

    • When this option is not specified, VMoveCAE exports the full vector/sixdof/tensor into the CAX file. The derived types are computed from the averaged component values.

    • Specifying the DERIVED value makes VMoveCAE compute the derived types before averaging.

    • Supported values:

    Result Type

    Derived Types

    Vector

    X

    Y

    Z

    MAGNITUDE

    Tensor

    XX

    YY

    ZZ

    XY

    YZ

    XZ

    VON_MISES

    MAX_PRINCIPAL

    MIN_PRINCIPAL

    MID_PRINCIPAL

  • THRESHOLD: Percentage of averaging threshold to be used during the nodal value computations.

    • Abaqus nodal value computations use a threshold percentage to identify discontinuities and determine whether to use averaged values or retain non-averaged values.

    • This option serves similar purpose.

    • The averaged value is retained only when range of weighted nodal value range is less than the threshold for the whole region.

    • This option is valid only when the derived type is specified. It is ignored otherwise.

    • Default value: 100%

  • BTR_TYPE: Tells VMoveCAE to retain the max/min value when the averaged nodal value is more than the threshold value.

    • CAX files can retain only one value per node.

    • When the weighted nodal value range is beyond the threshold value, user can specify VMoveCAE to retain the MAX or MIN value for that node.

    • Default value: MAX.

Examples & Description

Example 1

* RESULTS

-  U
-  S
-  NT
  • Exports displacement, temperature and stress to the CAX file.

  • All other resulted are ignored.

Example 2

* RESULTS, UNSPECIFIED=TRANSLATE

-  COPEN, FILTER
-  CPRES, FILTER
  • Filters contact opening and contact pressure.

  • Exports all other results to CAX file.

Example 3

* RESULTS

-  U
-  S
-  S, DERIVED=VON_MISES, THRESHOLD=75
-  E, DERIVED=VON_MISES, THRESHOLD=75, BTR_TYPE=MIN
  • Exports displacement and stress to CAX file.

  • Two stress results are written into CAX file.

  • Averaged stress component values are computed at the nodes and the full stress tensor is exported into the CAX file.

  • The CAX file will also contain the Von Mises stress values computed at the nodes with an averaging threshold of 75%. For the nodes with ratio of the range is beyond the threshold value, maximum values of stress are exported.

  • Von Mises strain values also get exported into the CAX file. For the nodes with ratio of the range is beyond the threshold value, minimum values are exported.

  • Other results are filtered out and not exported into the CAX file.

Example 4

* RESULTS, UNSPECIFIED=TRANSLATE

-  S, DERIVED=XX, THRESHOLD=75
-  S, DERIVED=VON_MISES, THRESHOLD=75
  • Exports all the results into CAX files.

  • None of the results are filtered.

  • Two stress results are exported. The first one is the X-component of stress with 75% averaging and the second one is the Von Mises stress with 75% averaging.

  • Other results are exported with the default settings.

* RESULTS, UNSPECIFIED=TRANSLATE

-  S, POSITION=E
  • Exports all the results into the CAX file.

  • Exports elemental stresses and not nodal stresses.

  • Other results are exported with the default settings.

Example 6

* RESULTS
