Full Field Views Using Partial Solutions
This example demonstrates how users can view a full solution field even though the model is only partially solved using symmetry boundary conditions.
This post-processing technique works with all solution types, even with the motion solver (check out the animations below).Symmetry boundary conditions are commonly used to speed up the computation of the solution and reduce the required disk space of the solution by solving only part of the geometry of the model and specifying how the solution will behave in the unmodeled portions.Examples of symmetry boundary conditions are even periodic, odd periodic, field normal and flux tangential.The script to automatically load the copied fields is available to maintained customers as a Free Add-On in the Customer Support section of the Infolytica web site.Full Field Display Examples

These are only some examples of how this unique feature can be used to minimize solving time and disk space while still allowing the engineer the ability to examine the full solution. This feature has no limitations on the kind of devices that can be modeled, which solver can be used or which fields can be visualized.
