# Self-consistent model to estimate the critical current of superconducting devices

#### This model was shared by V. Zermeno, Karlsruhe Institute of Technology.

The model presented here is used to estimate the critical current of superconducting devices. Its implementation is very simple either using finite-element-based or general numerical analysis programs. The model runs very fast, even on a laptop computer, making it a useful tool for optimization. In general, the model is very flexible and can be applied to many superconducting devices including transposed cables, single tape coils, coils made of transposed cables, non-transposed cables and cables with ohmic termination resistances.

The main description of the model can be found [here](https://iopscience.iop.org/article/10.1088/0953-2048/28/8/085004).

Several implementations for estimating the critical current of a 10 strand Roebel cable using COMSOL, MATLAB/Octave and FreeFEM++ are given below. The codes are fully commented and described [here](https://arxiv.org/ftp/arxiv/papers/1509/1509.01856.pdf).
