Products and versions covered


Issue:

The traces flow without a problem in Autodesk CFD but when animated, they typically show no movement, have very rapid movement, or freeze.

Causes:

A trace is taking too long or too quickly to pass through the domain causing the others to appear instantly relative to the these traces.

Solution:

  1. Edit the Trace
  2. Sort by Residency time
  3. Delete any residency time that is not within an order of magnitude of the majority of the traces
  • For Example:  Majority of the traces have a residency time of around 1e-1.  However there are some traces that are 1 second and some are 1e-2 seconds.  Delete the 1 second and 1e-2 second traces.
  • All the traces will have the same relative time and will animate smoothly.
