Is there a python equivalent of the PiecewiseCubicPolyProfile.fromUniformData function in the MATLAB interface?

[soumi]

Hello,

I have used the PiecewiseCubicPolyProfile.fromUniformData function in MATLAB to obtain sections/ polynomial coefficients for a ‘custom’ inlet protein/ salt profile.

I’m trying to port this to the python front-end. This might simply be my inexperience in python speaking, but is there a similar function to do this here?
I seem to explicitly define each section (i.e., ‘section_XXX’) and feed it its polynomial values. Is there an obvious way I’m missing to loop over this? (Except, perhaps, using an eval() )?

Thanks!

Hello soumi,

there is no such feature (yet) in CADET-Python but you can find a snippet in an older thread on the forum:

Inlet profile from data

Hey Lukas, to create an inlet profile from experimental data, you need to configure the piecewise cubic polynomials of the Inlet Unit Operation. For this purpose, you create a separate section for every ‘piece’. To automate that, you can use some helper function. Assuming some arrays for time and data_points, import numpy as np time = np.arange(5) data_points = np.array([ [0.0, 0.0], [0.0, 0.1], [0.5, 0.2], [1.0, 0.1], [0.5, 0.0], [0.0, 0.0] ]) you can write a he…

Thanks - that’s helpful.
