The Read Extended Variables tool gives you access to additional variables from the
AcuSolve solution database. This allows post-processing and
visualization of additional quantities, but comes at the expense of slower read
times.
If active, the extended and derived quantities are added to the nodal output variables to form
the variable list that is presented to you. The extended variable list can be
expanded further by setting the environment variable FV_ACUSOLVE_GRAD. This will
cause
AcuFieldView to read the gradients of the
transport variables. By allowing you to specify whether the extended variables
should be read gives additional control, allowing for faster read times and more
succinct data inquiry.
Note: In releases of AcuFieldView
prior to Version 13.0 the option to read extended variables was on by default
and was controlled by an environment variable.
