Errors on AeroDsk

[chamath01]

The following limitations were identified when using AeroDsk:
Minimum number of TSR values: 10
Minimum number of pitch values per TSR: 5
Each TSR should contain 0 degrees as the pitch
Minium Blade radius: 20 m
What is the reason for these limits, and are there any solutions to reduce these further, especially the radius, since I am working on small-scale wind turbines.

I'm closing this duplication of issue #2968.
