I think I found out what the problem was. I had no inertial properties for the aircraft

Hi, I'd like to try and use XFLR5 to find the different stability modes for a flying wing. We're using a slightly unconventional design, where we're using elevon deflection to stabilize the aircraft. After confirming that the design is stable by checking the Cm vs alpha graph and the Cm vs CL graph, I tried starting a stability analysis, but it can't find the eigenvalues somehow. Here's the log: xflr5 v6.39 11.11.2017 01:43:21 Launching the 3D Panel Analysis.... Airbox 11 Smoothed Transition Type...

Tried it at different AOA's and still no luck. Here's the log: xflr5 v6.39 11.11.2017 01:43:21 Launching the 3D Panel...
