Running Netfabb Simulation

Thermal analysis

To run the model, from a command line run:

$ pan -b ht_bench_t

The analysis progress is written to file ht_bench_t.out. To check progress run:

$ tail ht_bench_t.out

After the analysis completes, the last few lines of the output file ht_bench_thermal.out should be similar to the following:

Quasi-static mechanical analysis

Run the mechanical analysis from the command line:

$ pan -b ht_bench_m

The analysis progress is written to the file ht_bench_m.out. To check progress run:

$ tail ht_bench_m.out

After the analysis completes, the last few lines of the output file ht_bench_m.out should be similar to the following:
