 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.

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>

+==== 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".
