Import and Classify

Import the TSurf model and classify the components.

Using the Import and Classify tools, you will import the provided TSurf model into the HyperWorks session; classify the model components based on their relevance.

Import pre-made surfaces (tsurfs in this tutorial) and/or points (a csv file here) to define the model domain. The individual tria(ngular) or quad(rilateral) elements making up the surfaces are often called 2D or shell elements.

Import

Import the TSurf model.

You will import the tutorial TSurf model files using the Import feature.
  1. Start HyperWorks X from HyperWorks 2021.1 installation.
  2. Select Directors > GeoD.
    GeoD menu entry will be created. Click GeoD
  3. From I/O group, click Import.
    GeoD - Import dialog appears.
  4. Click .
    A file browser window will appear. Browse and select the tutorial files mentioned in the File Required section.
  5. Select all the TSurf files from the folder.
    You can observe that the File Type column states the selected file type.
  6. Select Meters for all components from under X-Unit, Y-Unit and Z-Unit columns.
    This defines the measurement units in the respective direction for the model being imported.
  7. Accept the default selections for other options and click Import.
    This will import the selected TSurf model into the HyperWorks X session.

Classify Model

Use Classify tool to classify TSurf model and its components.

After import it is necessary to classify and date the imported surfaces. The classification and age assignment provides the logical basis for subsequent clean-up operations. Whilst these operations can be applied on unclassified or undated features, the geological rules underlying them are not employed and unexpected results may occur.

Important: It is strongly recommended that you classify and date all the objects defining your model.
  1. Once the model is imported, Classify user message will appear to classify the model. Click Close.
    If not, you can launch the tool from Prepare Classify. This also launches the Model - GeoD tab for model classification and age definition.
  2. Click to switch to Flat Part View.
    Figure 1.
    Note: If you close the Model - GeoD browser, click Classify from ribbon to re-launch it.
  3. Define the age of components under Age column as below-
    Component Age
    Horizon Top 15
    Horizon-A 25
    Horizon-B 35
    Horizon-C 45
    Horizon-D 60
    Horizon-E 75
    Horizon-F 85
    Horizon Bottom 100
    Fault-A 10
    Fault-B 9
    Fault-C 8
    Note: For the purpose of this tutorial, the ages of the components are normalized from zero to hundred.
  4. Use the drop down list against each component, under the Classification column to classify the components. Classify the components as below:
    Component Classification
    Horizon Top Model Boundaries: Upper
    Horizon-A Geological: Formation Horizons
    Horizon-B Geological: Formation Horizons
    Horizon-C Geological: Formation Horizons
    Horizon-D Geological: Formation Horizons
    Horizon-E Geological: Formation Horizons
    Horizon-F Geological: Formation Horizons
    Horizon Bottom Model Boundaries: Lower
    Fault-A Geological: Fault
    Fault-B Geological: Fault
    Fault-C Geological: Fault
  5. Once the model classification is done, click to switch to Hierarchical Part View.
    Your model classification and age definition should be as displayed below.
    Figure 2.
    Tip: You can keep the Model - GeoD tab open during the complete session.
