Running Netfabb Simulation

Thermal analysis

To run the model, from a command line run

$ pan -b 09_thermal

The analysis progress is written to file 09_thermal.out. To check progress run

$ tail 09_thermal.out

After the analysis completes, the last few lines of the output file 09_thermal.out should be similar to the following:
