Co-processing is the fact of doing post-processing during solver
runtime. This page presents different possible extractions. You
can of course combine them in your compute script.
If you don't have a t.cgns or a tc.cgns to try this tutorial,
download these: [Download sample t.cgns][Download sample tc.cgns].
The bare computation file is compute.py.
Extraction of statistics
The extraction of statistics is triggered by
FastS.createStatNodes. An example
of script with statistics computation at each time step
is provided in computeStats.py.
Extraction of iso-Q criterion
We compute the Q-criterion in centers with FastS and process the
iso-surface directly on the mesh in centers.
Try: computeQ.py
Extraction of field on entities
Extraction of fields at some cell centers can be performed
with C.getValue. An example is provided here:
computeExtract.py.
Extraction of fields at some points defined geometrically or
at some entity nodes can be performed using
P.extractMesh. An example is provided here:
computeExtract2.py.
