Probe finite element solutions in points defined by various geometrical probes.
Generation mode
Probe the data in the results file corresponding to the problem defined in the
input file. The input file options must contain ‘gen_probes’ and ‘probe_hook’
keys, pointing to proper functions accessible from the input file scope.
For each probe returned by gen_probes() a data plot figure and a text
file with the data plotted are saved, see the options below.
Generation options
-o, –auto-dir, –same-dir, -f, –only-names, -s
Postprocessing mode
Read a previously probed data from the probe text file, re-plot them,
and integrate them along the probe.
Postprocessing options
–postprocess, –radial, –only-names
Notes
For extremely thin hexahedral elements the Newton’s iteration for finding the
reference element coordinates might converge to a spurious solution outside
of the element. To obtain some values even in this case, try increasing the
–close-limit option value.
