Define Porous Domains
Use the Porous tool and its satellite icons to define Cartesian, cylindrical, and spherical porosity on solid bodies.
Define Cartesian Porous Media
-
From the Flow ribbon, Porous
tool group, click the Cartesian Porous Media tool.
- Select solids.
- Click Orientation on the guide bar.
-
Position the porous media orientation in the following ways:
- Left-click on the model body.Tip:
- Use snap points to position the orientation on existing points, lines, surface centers, etc.
- You can move the orientation point after its been placed by selecting a new point on the model.
- Click in the microdialog to reposition the orientation point with precision using the Move tool. After moving, press Esc to return to the current context.
- Click in the microdialog to position the orientation using the Vector tool. Once the orientation has been defined, press Esc to return to the current context.
- Left-click on the model body.
-
Define direction permeability in the following ways:
- Enter values in the K1, K2, and K3 text boxes in the microdialog.
- In the modeling window, click an arrow on the triad, enter a value, then press Esc.
The triad is the same color as the global coordinate system. Based on that, you can map the direction number (X > 1m, Y > 2, Z > 3). -
Define the Darcy and Forchheimer coefficients in the following ways:
- Enter values in the microdialog.
- Click to calculate
the coefficients using thickness, density, viscosity, and a velocity and
pressure drop curve.Tip: Click Data and Fit below the plot area to toggle their visibility.
-
From the guide bar, execute the command in the following
ways:
- Click to confirm your selection and remain
in the tool.
This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.
- Click to confirm your selection and remain
in the tool.
Define Cylindrical Porous Media
-
From the Flow ribbon, Porous
tool group, click the Cylindrical Porous Media
tool.
- Select solids.
- Click Orientation on the guide bar.
-
Position the porous media orientation in the following ways:
- Left-click on the model body.Tip:
- Use snap points to position the orientation on existing points, lines, surface centers, etc.
- You can move the orientation point after its been placed by selecting a new point on the model.
- Click in the microdialog to position the orientation using the Vector tool. Once the orientation has been defined, press Esc to return to the current context.
- Left-click on the model body.
-
Define the Darcy and Forchheimer coefficients in the following ways:
- Enter values in the microdialog.
- Click to calculate
the coefficients using thickness, density, viscosity, and a velocity and
pressure drop curve.Tip: Click Data and Fit below the plot area to toggle their visibility.
- Enter radial, axial, and tangential permeability values in the microdialog.
-
From the guide bar, execute the command in the following
ways:
- Click to confirm your selection and remain
in the tool.
This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.
- Click to confirm your selection and remain
in the tool.
Define Spherical Porous Media
-
From the Flow ribbon, Porous
tool group, click the Spherical Porous Media tool.
- Select solids.
- Click Orientation on the guide bar.
-
Position the porous media orientation in the following ways:
- Left-click on the model body.Tip:
- Use snap points to position the orientation on existing points, lines, surface centers, etc.
- You can move the orientation point after its been placed by selecting a new point on the model.
- Click in the microdialog to reposition the orientation point with precision using the Move tool. After moving, press Esc to return to the current context.
