foil_worker don't accept any input for mach number #32

Closed emdotjay closed 6 months ago

emdotjay commented 1 year ago

Neither the helper for polar inputs, nor the foil_worker don't accept any input to specify the mach number. But the xoptfoil-jx do accept a mach number specification:

e.g: mach(1) = 0.55

Hi, .. this is right. I'll fix it in the next version. Are you able to compile by yourself?

Hi,

sorry but I'm not able to compile it by my self.

And at the moment I'm not sure if xoptfoil-jx also accept the mach number specification.

I use xoptfoil for a aircraft design class. The objective function is reducing the overall drag in the range of 0.6 < CL 0.8 at Re=2E7 and Ma=0.55. Your code produce a "smoother" geometry than xoptfoil, but the former codebasis converge fast to a result.

Hi, ... I'll have a look on the Mach number implementation (never used it before) and fix it in the next version ... regards Jochen

... sorry - it took a while ...

Optimization and polar generation with Mach numbers are now supported in Xoptfoil2 - see here
