Analysis of assemblies dynamic thermal performance behaviour under ISO 13786-2023

Thanks to the community members for being patient with my questions.

Although a lot of guys in the PTC community gave me  valuable tips,

I still want to improve my code slightly (perfectionism).

So, I'll try to list  of what do I want to get from my  code:

1. Define all the calculus dependencies in the first step.
2. Define the variables' range (each layer generally has its range). The idea is to account for all possible permutations.
3. The k1 and f functions should be figured out for each set of thicknesses (variable) iteration of my multilayered assembly (I have no idea how to assign a specific range of thickness to a particular layer; this is my weak point; I’m not confident in this area).
4. To sort out what of the total k1 and f values fit the restriction condition and arrange the result in a matrix with headers (for convenience, with aggregated values’ Names) (the particular matrix components should be plottable afterwards).
5. The number of layers varies, so I need to script the sequence of each iteration by indexing (I'm a bit frustrated in this regard right now).
6. The desired code has to be as compact and optimised ( in terms of machine time consumerance) as possible (the maxima goal).

Firstly, I tried to make it more generalised (with indexing), but the understanding of the leakage of base coding skills became evident very quickly.

I also understand that poor code is better than its absence.

For clarification, I attached my code in MathCAD Prime 10.0.0 and asked for assistance (advice, somehow) on how to deal with it.

I would appreciate any help.

I've attached my modified code and working sample for two layers.

PS. I also cannot understand why Chat GPT always creates JS-based code for my appropriate MathCAD prompt.

Best regards and thanks in advance.
