Create preview 3D


The Create preview 3D command is a special function available only in Flux Skew. It allows users to move to a dummy scenario called PREVIEW3D from which it is possible to:
  • Verify that the 3D skewed geometry generated by the extrusion performed by Flux Skew and the corresponding physical description are correct.
  • Create sensors before solving the actual users' scenarios. In Flux Skew, this procedure allows a faster evaluation of the sensors when compared with sensors created after solving.
    Note: Remind that this is a specificity of Flux Skew. In all other modules (Flux 2D and 3D), sensors may be created before solving a scenario without any special command.

How to preview the geometry in 3D

To create the PREVIEW3D scenario:

  • While in pre-processing, go to the Solving menu.
  • Then, select the Create preview 3D command.
  • Flux Skew will then ask for a project name for saving it. The user may choose a new name for that project or overwrite it by providing the current project name.
  • At this point, Flux Skew will build a scenario called PREVIEW3D, which becomes automatically active. The user can then explore the skewed design in 3D and eventually create sensors.
    Attention: The dummy PREVIEW3D scenario is considered solved, but contains no results. Consequently, several post-processing actions do not make sense in this context and must not be invoked. Further details are provided in the next section.

Allowed post-processing actions within the PREVIEW3D scenario

The most important actions that are allowed in the PREVIEW3D scenario are summarized in Table 1 below. The availability of the same actions in the regular 2D context of Flux Skew (before solving) and in a proper scenario (after solving) are also shown in that table, for the sake of comparison.

Note: Running the command Create preview 3D is not mandatory for the users who want to create sensors after solving a scenario.

Transitioning between the pre-processing (2D view), preview 3D and post-processing contexts (Regular solved scenario) of a project in Flux Skew

Figure 1 below illustrates the different states of a Flux Skew project and the actions required to transit between them.
