![]() Please consult the ParaView website to access their documentation and other technical resources. Lumerical does not provide technical support for Paraview. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. ParaView is an open-source, multi-platform data analysis and visualization application. While these functions are sufficient for the majority of data analysis, there may be situations that require more sophisticated tools. Lumerical's software provide a variety of built in data visualization functions, including line, image and vector plots. The colour of the vectors is defined by their alignment along the Mx, My or Mz axis of the simulation, from negative to positive (blue to red).Learn how ParaView can be used to create advanced visualizations of Lumerical simulation data. Lowering the value of the ‘Isosurfaces’ in the contour object Properties tab from the default value of 100 to a lower value, in this example 40, lowers the necessary helicity value at which a surface is created. Changing the ‘Glyph Mode’ to ‘Every Nth Point’ and increasing the ‘Stride’ value reduces the number of vectors displayed, only every Nth vector, where N = ‘Stride’, is displayed. The density of the magnetic vectors and the size of the magnetic vectors can be changed using the ‘Glyph Mode’ and ‘Scale Factor’ options respectively. The example magnetic state before and after adjustment is shown in Fig.20. Both can be adjusted in the Properties tab. The glyph object contains the magnetic vectors. The contour object is a surface which is taken at a specific level of helicity, and is used the show the core of magnetic vortices in the magnetic states. The two which can be used to control the visualisation are the ‘Contour1’ and ‘Glyph 1’ objects. This will load the magnetic states into the objects shown in Fig.19. The Properties tabs for both the Glyph1 (middle) and Contour1 (bottom) are also shown, with the editing options highlighted in red Using the arrows at the top of the window.įig.19 shows the Pipeline Browser with the two magnetic state objects, Contour1 and Glyph1, highlighted in red (top). ![]() tec files, for example in a hysteresis simulation, these mult_tec files will appear as a single option here, selecting this will open all of the magnetic states, which can then be cycled through. In the case that the simulation produces multiple. tec file is selected, these windows are shown in Fig.18. Selecting the ‘…’ icon will open another prompt. This loads the ‘Fix Paths in State File’ prompt. Here the ‘Takeshi X 0mT.pvsm’ should be chosen, not the. tec files are loaded using the ‘Load State…’ function. These can be visualised in Paraview, allowing the individual steps in any simulation to be analysed, whether these steps are steps in external field, temperature or different random states. tec files of each of the magnetic states at each simulation step. ![]() Micromagnetic simulations using MERRILL produces.
