AVL Tutorial (3) - Run-case (flight conditions) and Mass Distribution

This AVL Tutorial - Part 3 - will teach you about run-cases (flight conditions, trim etc.) and about the mass distribution file for the aerodynamic and flightmechanical analysis in the Athena Vortex Lattice (AVL) Code, which is very useful for quick and reliable Aerodynamic Analysis, Trim Calculation, Dynamic Stability Calculation.
I used this program extensively in my Bachelor Thesis and further works on the battery-electric touring motorglider FVA 30 (www.fva.rwth-aachen.de/), as a research assistant at the Flight Systems Dynamics Institute of RWTH university (www.fsd.rwth-aachen.de/) and for personal UAV and model aircraft design.
AVL was written by Mark Drela and Harold Youngren (Massachusetts Institute of Technology).
"AVL is a program for the aerodynamic and flight-dynamic analysis of rigid aircraft
of arbitrary configuration. It employs an extended vortex lattice model for
the lifting surfaces, together with a slender-body model for fuselages and nacelles.
General nonlinear flight states can be specified. The flight dynamic analysis
combines a full linearization of the aerodynamic model about any flight state,
together with specified mass properties."

Thanks you!

Hello, a very helpful series, but the model aircraft I tried to analyze is stuck on reading airfoil, even though the direct path is already stated in the .avl file. I exported the plane from XFLR5. Please help, thank you.
