File and Directory Structure

Use of many files

-Not one large common database

-For faster input/output

All files are usually associated within a Project

-Establishes working directory

-Settings (*.prj) file

Primary file types:

Tetin (.tin): Geometry plus

.Geometry entities and material points

.Part association

.Global and entity mesh sizes

.Created in Ansys ICEM CFD or Direct Cad Interface

Domain file (.uns)

.Unstructured mesh

Blocking file (.blk)

.Blocking topology

Attribute file (.fbc, .atr)

.Boundary conditions, local parameters & element types

Parameter file (.par)

.solver parameters & element types

Journal and replay file(.jrf, .rpl)

.Record of performed operations (echo file)

Mouse Usage

‘Dynamic’ viewing mode (click and drag)

-left: rotate (about a point)

-middle: translate

-right: zoom(up-down) screen Z-axis rotation (sideways)

-Wheel zoom

Selection mode (click)

-left: select (click and drag for box select)

-middle: apply operation

-right:unselect

-F9 toggles the mouse control to Dynamic mode while in Select mode

-Spaceball allows for dynamic motion even while in select mode
