Dear OpenVSP community, I am experiencing some issues whenever I press the launch solver for P, Q and R ANALYSES, whereby, each analysis takes at least two hours to show the results. I need to know whether or not this is normal. I have attached my settings on the VSPAERO tab

Also, for the Cruising Speed MACH of the B777-200ER (0.84), if I put 0.84 I get a warning that transonic flow is not supported. Is this normal? Or should I go with 0.8 Mach?

I have attached the screenshots
