Examples
el.elem = 'elcplgenint'
el.g{ig} = geomnum
el.var{ivar} = varname
el.global = varlist
el.src{ig}{edim}.ind{srcdomgrp} = domainlist
el.src{ig}{edim}.expr{ivar}{srcdomgrp} = srcexpr
el.src{ig}{edim}.ipoints{ivar}{srcdomgrp} = ip
el.src{ig}{edim}.iorders{ivar}{srcdomgrp} = io
el.src{ig}{edim}.frame{ivar}{srcdomgrp} = frame
el.geomdim{ig}{edim}.ind{eldomgrp} = domainlist
el.geomdim{ig}{edim}.usage{ivar} = eldomgrplist
The elcplgenint element accepts the same syntax as the elcplscalar element
with the only notable exception that a destination operator dest(subexpr) can be
used in the source expression. The destination operator’s argument will be evaluated
on the destination point instead of on the source domain. This can be used to
evaluate convolution integrals.
The integral is evaluated for each destination point, whether the dest() operator is
present in the source expression or not. Use an elcplscalar element if there is no
destination dependence.
