Creating and Editing Datasets

You can work with private and user-defined datasets in the Edit Dataset tab of the AMat.pro Builder.

Within this tab you can:

To edit an existing dataset:
  1. Select the Edit existing Dataset subtab of the Edit Dataset tab.
  2. In the Dataset textbox, enter the number of the dataset you want to edit and click search.
  3. To change one of the general information of the selected dataset on the left hand-side of the tab (see Edit Dataset Panel Reference), activate the relevant checkbox, and do one of the following:
    OptionDescription
    Edit information directly.
    1. Edit information within the editing box in the center of the tab.
    2. Click Save.
    Copy information from another dataset within the same database.
    1. Enter the relevant dataset number in the copy selected from text box.
    2. Click Copy.
  4. To mark the dataset as being recommended for the respective material property, click Set next to the Recommended option. The background color of the Recommended option switches from red to green.
    This option is only available for private material datasets.
    When Set, the background color of the Recommended option switches from red to green.
  5. To provide source, reference, or specimen files for the dataset, do one of the following:
    OptionDescription
    Add source or reference files.
    1. Next to the Source /Reference option click Set.
    2. In the Select File dialog, browse to the relevant file.

    The selected files are then copied to the scmat/11.02.003/win64/resources/references subdirectory of your STAR-CCM+ installation directory.

    Add specimen files.
    1. Next to the Specimen option click Set.
    2. In the Select File dialog, browse to the relevant file.

    The selected files are then copied to the scmat/11.02.003/win64/resources/specimen subdirectory of your STAR-CCM+ installation directory.

    These options are only available for private material datasets. You need to have write permission on the directories to add files.
    When Set, the background color of the selected option switches from red to green.
  6. To modify the actual dataset, select the relevant cell within the dataset table (see Edit Dataset Panel Reference), modify the values as required, and click Save Table.
    Use the AddRow (add row) and DelRow (delete row) buttons to edit the table dimension.

    The database plot is updated accordingly.

  7. If the physical property that owns the dataset is Fraction Solid, enter the value of latent heat in J/g within the Latent Heat textbox and click Save Latent.
  8. To control the style of the dataset curve, choose the appropriate style (see Edit Dataset Panel Reference) from the Select Curve Style drop-down menu.


To add a new dataset to a specified material property:
  1. Select the Add new Dataset subtab of the Edit Dataset tab.
  2. Within the Select Material group box, in the Material textbox, enter the name of the material (or a related string) and click search.
    If you want to see the complete set of material designations that are available, leave the Material textbox empty.
  3. In the Material Search dialog, choose the corresponding material designation and click Select.
    The material designation and the respective database ID are displayed.
  4. Within the Select Property group box, In the Select... drop-down list, select the appropriate physical property.
  5. To specify the source of the new dataset, within the Select File and Settings group box, do one of the following:
    OptionDescription
    Add a new dataset from a dataset input file.
    1. Select the From File subtab.
    2. Enter the required information, see Edit Dataset Panel Reference.


    Add a new dataset by duplicating the data from a specified dataset of the same database.
    1. Select the From Dataset subtab.
    2. In the Dataset textbox, enter the number of the respective dataset and click search. The material and physical property that own the specified dataset is displayed.


    Create a new dataset table.
    1. Select the From Table subtab.
    2. Click the AddRow (add row) and DelRow (delete row) buttons to dimension the table.
    3. Select the relevant cell within the dataset table, see Edit Dataset Panel Reference, and set the value as required.


  6. Click Add to save the new dataset to the database.
To delete an existing dataset:
  1. Select the Delete existing Dataset subtab of the Edit Dataset tab.
  2. Within the Select Dataset to Delete group box, in the Dataset textbox, enter the number of the dataset that you want to delete and click search.
    The material and physical property that own the specified dataset is displayed.

  3. Click Delete to remove the dataset irreversibly from the database.
To operate on datasets:
  1. Select the Dataset Operations subtab of the Edit Dataset tab and do one of the following:
    OptionDescription
    Extrapolate a dataset to a temperature value outside its temperature range.
    1. Select the Extrapolate subtab.
    2. Within the Select Dataset to Extrapolate group box, in the Dataset textbox, enter the number of the dataset and click search. The material and physical property that own the dataset is displayed.
    3. Within the Extrapolation Temperature Value [°C] group box, enter the required temperature value.
    4. In the Select Method group box, activate the Linear extrapolation method.

    5. Click Extrapolate to calculate the value at the specified temperature and add the data to the dataset.
    Reduce the amount of data within a dataset.
    1. Select the Reduce subtab.
    2. Within the Select Dataset to reduce group box, in the Dataset textbox, enter the number of the dataset and click search. The material and physical property that own the dataset is displayed.
    3. In the Set Rules group box, add up to three rules to define the data reduction. Each rule allows you to define a temperature interval in which the amount of data is reduced, see Edit Dataset Panel Reference.

    4. Click Reduce to delete the redundant data and save the reduced dataset to the database.
    Smooth the curve of a dataset.
    1. Select the Smooth subtab.
    2. Within the Select Dataset to Smooth group box, in the Dataset textbox, enter the number of the dataset and click search. The material and physical property that own the dataset is displayed and the dataset curve is plotted in the graphics box.
    3. In the Select Method group box, choose the appropriate method that you want to use for smoothing the dataset, see Edit Dataset Panel Reference. The profile is updated to give you a preview of the smoothed dataset.
    4. In the Smooth Level group box, choose the smoothing level as required, see Edit Dataset Panel Reference. The curve is updated accordingly.

    5. Click Save to confirm the settings and save the smoothed dataset to the database.
