GEMACS Screen Shots

GEMACS and XGAUGE

Description: 3m cylinder (1m diameter), excited by a vertical plane wave from the viewpoint of the user. Incident excitation is 376.7 V/m (H=1 A/m). Expectation is on average a 2 A/m surface current in the illuminated region. Current min is 0.0 (dark blue), max is 2.5 (bright yellow).

GEMACS input commands file: cyltest.gem
GEMACS geometry file: cyltest.geo

Description: F16 aircraft with an antenna behind the inlet. Excited at 100MHz up to 0.1 A/m surface currents on a dB scale.

GEMACS input commands file: FullF16.gem
GEMACS geometry file: FullF16.geo

SmartView 3D Visualizer

Description: Same cylinder as in previous XGAUGE example. Notice the smoother contouring achieved by SmartView with the OpenGL engine.

Description: Pattern from an underside antenna on the F16 aircraft. Excited at 100MHz with color contouring on a logarithmic scale. Viewpoint is looking at the underside of the aircraft, banked to the right.

G2GEM and CELLGEN

Description: Model generated by CELLGEN from original BRL-CAD model. Rendered in SmartView.

Description: Model of Ground Vehicle generated by G2GEM with a grid size of 10cm. Rendered in SmartView.

Description: Model of same Ground Vehicle as generated by CELLGEN with a grid size of 5cm. Rendered in SmartView.

Description: Grid model of the Comanche helicopter using G2GEM with a grid size of 5cm. Rendered in SmartView.

EigenTools

Description: Exploded view of compartments (rooms) in an office floor plan for use in demonstration of compartment-to-compartment coupling. The computational grid for this problem has 3,746 interior nodes, so it is small enough to compute all the eigenvalues and eigenvectors in a reasonable amount of time.

Mode 0: 13.537 MHz (mostly in region #7)

Mode 1: 30.202 MHz (mostly in region #9 but couples into adjacent regions)

Mode 2: 33.554 MHz (mostly in region #4 but couples into region #9 and somewhat into regions #2, #3, and #5)

Description: Contour plot of cavity fields at 70 MHz using the full eigenvector mode set. Description: Three-dimensional ISOContour plot of cavity fields at 70MHz using the full eigenvector mode set. The isocontour represents a field strength of 1 V/m.
