Creating And Editing Scenes

Scenes are graphics used to help the user visualise the geometry, mesh and the ‘solution’ variables. Scenes are a key feature of this program, and it is something you need to familiarise yourself with as it very useful to grasp what is being show.

A Geometry scene is used to view the object, its regions and surfaces.

Geometry

A Mesh scene is used to see the surface and volume mesh. It is important to view the mesh to see its construction of a body and how accurately it represent an object.

Mesh

A Scalar scene displays fields of variables across the body. It helps visualise the distribution of fields such as pressure across a body.

Scalar

A Vector scene displays vector fields across the body.

Vector

If you expand the scenes node on the main tree, you should see a list of other nodes (related to the scenes you have created) which lead to other sub-trees. If you expand one of those nodes, you should find a displayers sub-tree which is used to select the geometry (scalar and vector for scalar and vector scenes respectively) and its outline which are visible in the graphics pane. The part node in Geometry, Scalar and Vector allows you to select the objects visible in the scene. The part node in Outline can also represent the surface appearance.

Another function of Scalar is that it also allows you to select the scalar field function and its presentation and Vector can similarly allow you to select the vector function and its appearance.

The attributes sub-tree is used to customise the view in the graphics window, from changing the background colour to the scene lighting.

Vector_field

If you want to have a combined scene, for example, a scalar and vector scene in one you can right click on the displayers node and then hover over New Displayer to choose a scene you wish to add on the current one.
