Please ignore my last msg - I found rrt_sample.cpp on github (I only had what's in the conda implementation). And here's another question (sorry I keep pestering you with that!) In the main loop there are appear to be two commands that do the majority of the work:
ub_sampler->apply(dof_values[i]);
kfss->do_before_evaluate();
can you suggest which of those I will find what i am looking for ?
thanks
michael
