Flow Analysis Tab

When you open an assembly file, the Flow Analysis tab appears. The Flow Analysis tab contains the options for Flow Analysis to perform the simulation. The options are divided into the groups listed below:

Group	Icon Description
Project	Create, save, open, close, import, and export projects
Updates	Update projects or fluid domain, to modify the fluid domain when there are changes made to the CAD model
Simulation Domains	Create a fluid domain for a CAD geometry, split them and add them as simulation domains to perform calculations
Materials	Open the Material Selection dialog box
Operations	Generate the mesh, add physical modules, add boundary conditions, view tessellations in the CAD geometry, and start the expression editor
Show	Show CAD, Creo Flow Analysis bodies, and XYPlot Panel(Residual Panel)
Post-processing	Create sections, XY-plots, isosurfaces, streamlines, monitor points, and view grid and geometry related information
Run	Run, pause, and stop a simulation, control the start point of the simulation, and select steady or transient simulations
Close	Closes the Flow Analysis tab

Flow Analysis Tree

The Flow Analysis Tree is organized according to the Flow Analysis workflow. The Flow Analysis Tree provides access to the geometric entities such as CAD surfaces, boundaries, and domains in a project that you can manage for the analysis. The available entities are listed below:

• Physics—Physical modules used in the simulation

• Domains—Fluid domains in the model

◦ Redefine—Opens the Fluid Domain Creation tab where you redefine the domain.

◦ Add Boundary Condition—Adds a boundary. Opens the Surface Sets dialog box where, under Included Surfaces, you select the surfaces for a boundary

◦ Remove—Deletes the domain.

• Boundary Conditions—Boundaries of the fluid domain under General Boundaries

• Results—Entities created after meshing, and for postprocessing

◦ Derived Surfaces—Lists the created sections and isosurfaces

◦ XY Plots—Displays the quantitative results of the simulation

◦ Monitoring Points—Records variables or properties data at a specific location

◦ Streamlines—Tracks the path of flow

◦ Particles—Tracks particles of flow or particles moving with the flow

Functions Panel

From the Functions panel you can control the entities and your view of the entities in the Flow Analysis Tree.

Icon	Description
	Connects two boundaries to create the mismatched grid interface (MGI)
	Deletes the selected geometric entity
	Turns off the display of the selected entity and reverts to the display of all entities
	Expands categories under the Flow Analysis Tree and displays all the entities
	Displays only the categories under the Flow Analysis Tree and hides all the entities under them
	Switches the display of CAD and simulation geometry
	Switches the view of the grouping for geometric entities. You can view as a hierarchy based on volumes or as independent categories, based on type.
	Switches between turning off and turning on the global display of all surfaces, grids, and outlines.

Properties Panel

The Properties panel contains information about geometric entities and physical modules. The parameters and conditions on the Properties panel depend on your selection in the Flow Analysis Tree. This panel contains the Model tab and the View tab.

• Model Tab

◦ Mesh-related parameters—Appear when you click Domains in the Flow Analysis Tree.

◦ Physical module-related parameters—Conditions related to the physics being studied. Parameters vary according to the selection in the Flow Analysis Tree:

▪ Numerics, convergence, and more options appear when you select a module under Physics.

▪ Boundary conditions appear when you select a boundary under General Boundaries.

▪ Interface and MGI-related options appear when you select the entity under Boundary Conditions

▪ Volume-related conditions appear when you select a fluid domain under Domains.

• View Tab—Contains parameters to change the display in the Display window.

◦ Surface—Displays the primary variables (such as pressure, velocity or temperature), physical properties (such as density, viscosity), or derived variables (such as total pressure, velocity magnitude, enthalpy) when you select boundaries, derived surfaces, interfaces, CAD surfaces, and volumes. The options available under Surface are listed below:

▪ Keep drawing—Displays the surface of the boundaries, derived surfaces, interfaces, CAD surfaces, and volumes.

▪ Grid—Displays the grid (mesh) on boundaries, derived surfaces, interfaces, CAD surfaces, and volumes.

▪ Outline—Displays the outline on boundaries, derived surfaces, interfaces, CAD surfaces, and volumes.

▪ Number of Colors—Specifies the number of legend colors.

▪ Show values—Displays all values in the legend.

▪ Smooth Color Map—Changes display mode of the color bar.

▪ Local Range—Sets the color map range based on the local values in the entity.

▪ Min and Max—Adjusts the bounds for the color bar for contours.

◦ Vector—Displays vectors on boundaries, derived surfaces, interfaces, CAD surfaces, and volumes. The options available under Vector are listed below:

▪ Color By Function—Select a primary variable, physical property, or derived variables for display on the vectors.

▪ Color—Select a legend to associate with the display variable.

▪ Size—Controls the size of the vectors. These are also controlled by the slider bar.

▪ Uniform Head—Switch between uniform head size and head size depending on the vector magnitude.

▪ Head Size—Manually change the vector head size depending on your input.

▪ Projection—Project the vectors onto the selected surface.

Dialog Boxes for Creo Flow Analysis
