Previewing the 3D geometry and creating sensors in Flux Skew before solving

A new special function for Flux Skew module that enables the pre-visualization of the skewed 3D geometry and the creation of sensors before solving a scenario.

Introduction

Since Flux 2023.1, Flux Skew module has been upgraded with the Create preview 3D command which is a special function. A function that allows users to produce 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 evaluating sensors created after solving.

Where to find this special function

In Flux Skew module and for all applications while in pre-processing the Create preview 3D command can be accessed through the Solving menu as depicted in Figure 1.

At a second step a pop up window prompts for a project name (Figure 2). 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 (Figure 3). The user can then explore the skewed design in 3D and eventually create sensors.

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.

Important : Another consequence of this development is that the beta mode feature that allowed the initialization of state variables from the solution of a Flux 2D project is no longer provided in the graphical user interface of Flux Skew (for Magneto Static and Steady State AC). Consequently, in Solving process options (menu Solve→Edit, Advanced tab) , the option With 2D solution (beta) is no longer available from the Initialization of state variables at the beginning of a step drop-down menu. The corresponding python command remains available.

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

Figure 4 below illustrates the different states of a Flux Skew project and the actions required to transit between them.
