Running Netfabb Simulation

Thermal Analysis

To run the model, from a command line run:

$ pan -b symmetry_thermal

The -b option runs the solver in background mode, which automatically overwrites any previous results, and directs output to a an output file of the format input-file-name.out.

The analysis progress is written on file symmetry_thermal.out. To check progress in a linux environment run:

$ tail symmetry_thermal.out

To check progress in a Windows command line environment run:

$ type symmetry_thermal.out

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

Quasi-Static Mechanical Analysis

Run the analysis from the command line:

$ pan -b symmetry_mechanical

The analysis progress is written on file symmetry_mechanical.out. To check progress run:

$ tail symmetry mechanical.out

or in Windows:

$ type symmetry mechanical.out

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