 You can also display animations of time varying fields. Do not hesitate to consult [[https://docs.paraview.org/en/latest/UsersGuide/animation.html|Paraview animation documentation]] to learn how to best visualize time-varying data.
-<callout type="primary" icon="true">A SesamX non linear static resolution does not depend on time, but on the level number. However, the SesamX viewer makes no distinction and will treat each occurrence as a time in seconds. A static solution composed of 10 occurrences ranging from 1 to 10, will be seen, by the SesamX viewer, as a time-varying solution ranging from 1 second to 10 seconds.</callout>

 ==== Controlling the symbol size ====
-The line and point symbols (used for tensor and scalar fields) may sometimes be difficult to visualize. When necessary, **you can increase the point size and the line width**. To proceed, you need click on the gear icon in the properties panel, which shows hidden options. Then under the styling section you can control the "Point Size" and "Line Width" parameters.

+==== Disabling NaN visualization ====
+By default, the SesamX viewer can display fields with NaN data. An element or a node with a NaN value indicates that the underlying field does not have any data associated to this element or node. For instance, dummy coating elements used for the definition of contact condition cannot carry stress data.
+Unless otherwise specified, NaN values are displayed in yellow, and they can impair the view. Fortunately, Praview allows to control NaN display. Removing the NaN values is as simple as turning the NaN opacity to 0 in the "Color Map Editor".
