To run the original thermal model, from a command line run:
$ pan -b ht_bench_t
After the analysis completes, the last few lines of the output file ht_bench_t.out should be similar to the following:

Run the original mechanical analysis from the command line:
$ pan -b ht_bench_m
After the analysis completes, the last few lines of the output file ht_bench_mechanical.out should be similar to the following:

Actual CPU times may differ. Now the restart simulations are performed. First the thermal model is rerun:
$ pan -b ht_bench_t_restart
After the analysis completes, the last few lines of the output file ht_bench_t_restart.out should be similar to the following:

Actual CPU times will differ, but note the restart Wall time is about 1/3 of the original thermal simulation Wall time. Now run the new heat treatment mechanical simulation:
$ pan -b ht_bench_m_restart
After the analysis completes, the last few lines of the output file ht_bench_mechanical.out should be similar to the following:

Actual simulation times will differ, but again note the simulation time using the restarted input file is about 1/3 of the original simulation.
