2.5 WOOD MODEL OUTPUT
One example output file is given here for completeness. It gives the output format for the PINE and FIR options. If the <BLANK> option is selected, then the lines for wood type through units are omitted. The example values printed are for saturated grade 1 pine at room temperature in units of MPa, cm, and ms.
Printed for PINE and FIR options only.
