KNOWN ISSUE: CFD-Post may use incorrect mesh for sliding mesh cases in Fluent (Class 3 Error if it were not mentioned in errata)
When using CFD-Post for FLUENT results cases using the sliding mesh feature, independently of the time step selected CFD-Post will always use the mesh for the last time step. This means, for example, that animations will be incorrect.
This is due to incorrect implementation of the sliding mesh feature.
To work around this problem, exit from CFD-Post, set the environment variable CFDPOST_FORCE_FLUENT_MESH_UPDATE to a value of 1 and restart CFD-Post.
