control points

[EVElove444]

I am using WEIS/WISDEM (version: [e.g., WEIS 1.6 / WISDEM 3.x]) to optimize wind-turbine blades with the control-point parameterization for twist, chord, and laminate thickness (e.g., settings like n_opt, index_start/index_end, and max_increase/max_decrease).
Which method is used to generate continuous spanwise curves for chord and twist from control points? For example, piecewise linear, cubic spline, B-spline, Bézier, PCHIP, Akima, etc.? and laminate thickness (e.g., spar caps）

WISDEM uses the PCHIP interpolator in SciPy.

@gbarter Where can I find the specific documentation or the relevant code?

There is extensive code to build the blade from the WindIO inputs. The two main files where this occurs are:
