PMARC (Panel Method – Ames
Research Center) is a panel-method aerodynamic analysis code developed at
NASA from about 1980 to the late 1990’s, through a sequence of versions
culminating in PMARC 14. PMARC 14 has probably never been publically
available from the government, but commercial versions of it exist. PMARC
12, on the other hand, is in the public domain (including source code),
and has been freely available for years. MultiSurf 6.9 has features
for exporting panel models in either PMARC 12 or PMARC 14 formats. This
document provides step-by-step guidance for the use of MultiSurf for
generating PMARC input files. The example model file
Wing3.MS2 has been prepared as a test case; it is referred to frequently
below to illustrate various points. Wing3 is a swept tapered wing with
symmetric sections, nominally at zero angle of attack. The model has real
parameters that control root chord, span, thickness, sweep angle, taper
ratio, angle of attack, and wake length. An appendix of this document
explains the structure of the Wing3 model. |
