Running Netfabb Simulation

Thermal analysis

To run the thermal model without powder, from a command line run

$ pan -b t0

The analysis progress is written to file t0.out. To check progress run

$ tail t0.out

After the analysis completes, the last few lines of the output file t0.out should be similar to the following:
