no convergence behaviour

[pl96andy]

Description

When trying to calculate airfoil and xfoil is failing to converge, i receive error that airfoil is failing to converge and program terminates execution I guess there is no much use of it because after receiving such information i wish to continue execution of my program

Current behavior

As an output i am receiving: ` Sharp trailing edge

Sharp trailing edge Paneling convergence failed. Continuing anyway...

This looks like an XFoil issue, not something specific to CMPLXFOIL. Try looking up what kind of thing might cause the paneling to fail in XFoil

of course cause incorrect airfoil geometry but problem is that code does not only return error but it also terminates process my workaround is to call CMPLXFOIL in separate child process for xfoil to kill its own process not main program i just consider necessity of such workaround is strange
