Spatial Plot
Description
This tool is used to determine the harmonic content of the electromagnetic forces (by using Altair Flux) in the motor airgap and to generate a related spatial plot for the NVH analysis.
1. Inputs
The input file for the tool can be: 1) a Flux-solved 2D transient magnetic analysis project (a .FLU file) or 2) a solved SimLab MT2D solution.
Case 1: by using a Flux-solved 2D transient magnetic analysis project (.FLU)
In this case, the user needs to manually indicate the target Flux project (.FLU), and define one of the speed values defined in the multi-speed simulation.
Case 2: a solved SimLab MT2D solution
Users can also get access to the Spatial plot tool in the [Results] ribbon of a MT2D solution in SimLab. When running this tool in an already solved MT2D solution, the tool will automatically locate the target Flux project (.FLU) and list all speed values defined in the solution. Users will only need to select one of the speed values to perform the spatial plotting.
2. Component
Two force components (radial or tangential) can be used for the spatial plotting.
3. Computational support definition (for Flux)
Forces are obtained by computed the magnetic flux density components along a computational support (a path) in the airgap. For the definition of the virtual support, two methods are available (by selecting or not the option “Auto compute input parameters”):
- [Recommended method] If the option is enabled, Flux will automatically determine the radius of the cylinder and its discretization.
- If the option is not enabled, the cylinder radius, the number of computation
points along the perimeter must be provided manually.
4. Plot settings
As the electromagnetic forces are obtained by computed the magnetic flux density components, currently, the tool supports two kind of plot type: Maxwell pressure plot or the spatial order plot.
Spatial Plots will be listed under Solutions Tab in Model Browser for each solution.
Spatial Plots can be shown/hidden based on icon check on/off.
Spatial Plots can be modified by double click in the browser.
Spatial Plots can be saved with the database.
Spatial Plots can be deleted using the delete option.
