Running Netfabb Simulation

Thermal analysis

From a command line run

$ pan -b 04_thermal

The analysis progress is written to file 04_thermal.out. To check progress on Linux, run

$ tail 04_thermal.out

or in Windows run

$ type 04_thermal.out

After the analysis completes, the last few lines of the output file 04_thermal.out should be similar to the following:

Actual CPU times will differ.

Results can be imported and viewed in Simulation Utility for Netfabb or ParaView. The results at three different time steps: beginning, middle, and end of the simulation, are shown in Figure 1.
