• To start Fluent Meshing

– On a Windows system: click on the Fluent shortcut icon and select Meshing Mode from the startup options

– On a UNIX system or from DOS type

• Fluent 3d - meshing

• Fluent launches in “Meshing Mode”

• Solver functionality “greyed out” until meshes moved into solver mode

• Precision and parallel options only relate to the Fluent solver processes which are spawned when volume meshes are passed to the solver

• Text interface and complete graphical user interface (GUI) from TGrid legacy software is available

• New “Vertical Workflow Ribbon” available under “Mesh Generation”

Reading Files You can read or import boundary mesh file(s) or

mesh file(s) into Fluent Meshing

• To read a boundary mesh (*.msh) use

– File -> Read -> Mesh… or Boundary Mesh…

• For other mesh formats e.g. ANSYS, Nastran, Patran, etc, use

– File -> Import -> Mesh

– STL must come in via File -> Import -> CAD

If your mesh is contained in two or more separate files, you can read them in together or separately using “Append File(s)” option

• Use the Filter option to list files with particular naming patterns using wildcard* syntax

• Use the Select All option to select all .msh files in the directory

Note if you read a volume mesh in using Read -> Boundary Mesh the cells will be ignored and only boundary mesh will be

imported. Use Read -> Mesh to read a volume mesh.

Graphical User Interface Operations

Selection in the GUI panel

• Select boundaries in the list using left mouse button (LMB)

• Supporting multiple selection/de-selection using Shift/Ctrl

• Toggles to Select All, Deselect all, Invert selection

• Selection filters using predefined or user defined Zone Groups available in many Fluent Meshing panels

Selection helper

• Display -> Selection helper

• Select or de-select all zones with a specific string

Selection in the TUI

• Minimum number of letters to uniquely define the selection is sufficient

– i.e. boundary = bou = bound = b at top level

• Use “/” or space to move between levels

• Hit “return” to see available options

• For multi-word options you can use first letter in each word

• Use “q” to go back

• Note that certain operations only exists in the TUI

• On/Off switches generally end with a “?”

Zone Selection in TUI

• Certain operations require the user to select zones

• The TUI supports wildcards as name “handles”

– wall*, *side*

– ID number can also be used

• Use “List” in Manage Zones to get Id numbers

Mouse Operations Mouse Operations • The mouse operations are controlled by the

Display -> Mouse Button panel

– Middle click centres the view on mouse pointer

– Downward diagonal box: zooms in

– Upward diagonal box: zooms out

• Right: Mouse-probe

– By default Select zone

• Deselect by clicking second time on same object

• E.g. RMB on boundary to select/deselect for display

– Can be modified using Display ->Mouse Probe panel or Short Cuts (see Lecture 3)

Setting Display and Graphic Options Display the grid in Display -> Grid

• To ensure that you are only displaying boundary zones select the boundary group in the Face Zone Groups filter list

• Best practice to never display all interiors/cells

– Selecting all face zones will also select volume interior faces so best to use boundary filter

– When Displaying cells reduce display bounds to a slice plane only in Bounds tab

The following options usually produce a nicer display

• In the Attribute options, turn on Filled and Lights

– For large models with very dense mesh, edges could be turned off

• In the Colors option, use Color by ID to differentiate between zones best

Setting Display and Graphic Options More Display Options • For further manipulation of the graphics,

open the Display Options panel

• Also available via Rendering… button in Display -> Grid

Key Display Options • For larger models Wireframe Animation

option is recommended for speed of rotation

• Double Buffering maintains rendering during graphic rotation

• It is recommended to activate Display Timeout when you display large volume meshes as sometimes accidents happen displaying many million volumetric elements

• Classic Color Scheme gives black background

User Preferences can be stored in a .tgrid configuration file.

Please ask your local support office or trainer for details

Demonstration In this demonstration, we will:

• Start Fluent Meshing

• Read in a good quality, “volume-mesh ready” boundary mesh file containing a simple surface mesh

• Inspect the surface mesh with the graphics window

• Show list selection of entities – position, node, edge, zone using RMB in graphics window

• Show how to zoom on an area of the mesh using Bounds in the workflow page after RMB on an entity

• Show how lists work e.g. invert selection

• Show usage of Boundary Groups

• Show usage of Zone Selection Helper

• Generate tet mesh

• Show cut-plane of tet mesh using Display Grid and Bounds

• Start recording a journal

• Use TUI to clear mesh, change growth rate and create tet mesh. Display.

• Stop journal and open in a text editor. Change growth rate and re-run journal

• Write Volume Mesh

Store TUI commands in journal (text) files to run operations in batch • Run using File -> Read Journal

Syntax used in Journal files • ; -> Comment line

• , -> Accept the Fluent Meshing default.

• () -> End a list of entity selection

(Note that ”,” can also be used in most cases but that () is the safest)

Example : ; read in a mesh

rm file.msh.gz yes

Advanced usage • Zone Query mechanisms exist for applying settings to zones based on

complex criteria – see User Guide Appendix

– Example : (get-face-zone-at-location '(x y z))

• Scheme commands

• Templates

Best Settings for Pictures

• Standard display colours both edges and faces by ID.

• Use Scene Description to change edge colour to black R=G=B=0
