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:

 inc = 38 time = 15831.914 iter = 1 eps = 0.45808E+02
