![]() ![]() The next step is to automatize all this using scripts. The use of Filters is not clear in the beginning, but after playing with some examples, everything becomes really easy to use. I heard that Paraview could to many things when dealing with visualization aspects, but I hesitated to use it until now since the interface is not straightforward. Then go to File/Save Animation to save it to a file. Once everything is set, click the play button to see the animation. You’ll be presented with multiple options, like the center of rotation, direction of the vertical and initial position. Add a Camera object with Orbit field selected. Just go to View and select the Animation box. You can also create animations in a pretty straightforward way. You can also symmetrize your geometry using the Reflect filter. Below you can see a result built from my work. The number of input and output ports on a filter is fixed. A filter can have multiple input and output ports. They take in data on their inputs and produce transformed data or results on their outputs. Many other features are directly available: you can color the level set following another scalar value, you can set the lighting, etc. Understanding filters In ParaView, filters are pipeline modules or algorithms that have inputs and outputs. The difference is that you need to specify two values and Paraview will draw the surface enclosing the points corresponding to these values. If you want to have a closed region instead, you need to use the IsoVolume filter instead of the Contour one. If your level-set cuts the boundary of the domain, Paraview will draw a hole there. You’ll have to select the field for which the contours will be drawn and then put in the values of the level-sets you want to see.
