Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE
studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
From the Geometry ribbon, click the Validate tool.
The Validate tool scans through the entire
model, performs checks on the surfaces and solids, and flags any defects in the
geometry, such as free edges, closed shells, intersections, duplicates, and
slivers.
The current model shows 13 surface related issues.
Click SurfaceChecks to open the surface repair
tool.
Fix Surfaces
In the SurfaceChecks legend, click Free edges (13) to
highlight all the free edges in the model.
On the guide bar, enter a value of
2.0e-4 for the stitch tolerance and click
Stitch All.
Observe that the number of free edges in the SurfaceChecks legend is reduced
from 13 to 7. The remaining free edges are large holes which will be
patched.
On the guide bar, click on the drop-down arrow next to
Stitch and select Patch Hole.
Click Patch All to patch up all the highlighted holes in
the geometry.
Observe that in SurfaceChecks legend you obtained a closed shell from
the prior operations.
Click Closed shells (1) in the SurfaceChecks legend and
then select Create All on the guide bar.
Press Esc to exit the
tool.
Save the model.
The Surface geometry is now converted into a solid geometry and can be
viewed in the Part Browser (View > Part Browser).
Extract the Fluid Domain
In this step, you will use the solid geometry to extract the internal fluid as a
part, which you will then use for the simulation.
Click the Plug tool.
Click Find on the guide bar.
All the holes which can be plugged are highlighted.
Left-click any one of the manifold openings (Inlet or Outlets).
On selecting the opening, all the other manifold openings are closed,
leaving behind the bolt holes on the flanges.
Press Esc to exit the
tool.
Open the Part Browser from the View menu if you have not
already.
You should see two SolidBody parts under the Body folder corresponding to the
solid shell and the fluid.
Right-click on SolidBody_3_1 and select
Delete.
The Fluid geometry is displayed in the modeling window.
Save the model.
Extrude Boundaries of the Fluid Domain
From the Drag/Spin tool group, click the
Drag tool.
Select the individual ports to highlight them.
Click on the individual ports to highlight them.
In the microdialog:
Disable Retain Shared Edges
.
Type a value of -0.2 then press
Enter.
This represents the length of the extrusion.
Press Esc to exit the
tool.
Save the model.
Defeature Faces
Small faces in the model can lead to poor mesh elements
during surface mesh. The edges corresponding to the faces can be defeatured to allow for
surface merging.
Switch the entity selector in the modeling window to Surfaces.
In this step, you will look at creating an interface
which, in most cases, is used to monitor average property values such as mass flux,
velocity magnitude, static pressure, and temperature. In this tutorial, you are going to
create interfaces along the manifold inlet axis and in between each port.
Click the Split tool.
From the secondary ribbon, click the Plane tool.
On the guide bar, change the Target selector from
Surfaces to Solids.
Select the manifold.
Click Tool on the guide bar.
Hover over the end of the inlet until the tool snaps to a point on the surface
boundary of the outlet, such as the Mid point.
Enter 1,0,0 as values for the unit vectors x, y, and z
in the microdialog then press Enter.
Click to open the Move
tool.
Double-click on the Z-axis arrow to open its input
dialog.
Enter a value of 0.5 and press Enter.
The tool shifts its position to the original outlet position.
Click Split in the microdialog
to execute the split.
The two solids are now connected by a single interface.
Click Target on the guide bar.
Select the right-most solid.
Repeat steps 5-11 with a z-displacement value of
0.65.
You should now have three solids separated by two
interfaces.
Click Target on the guide bar,
select the right-most solid, and repeat steps 5-11 with a z-displacement value
of 0.80.
You should have four solids separated by three interfaces as shown in
Figure 22.
Press Esc to exit the
tool.
Save the model.
Re-Validate the Geometry
Click the Validate
tool.
Observe that a blue check mark appears on the top-left corner of the Validate
icon.
This indicates that the tool found no issues with the geometry
model.
