Model Investigation: CS Tresca Stress Tresca yield criterion

[ym1906]

Context

As part of a review into PROCESS, we evaluated the Large Tokamak input file to find active constraints. This was done to aid prioritization of model development.

This reveled that the CS Tresca yield criterion was a limiting factor (constraint equation 072).

Task

We want to investigate this model to understand it better:

- Does the model make sense in isolation? Is it continuous are or there discontinuties?
- Run the model in isolation for realistic values and plot the results
- Has the model been bench marked against anything (experiments, literature, other codes) ?
- Does the documentation reflect what it is doing?

Outcome

Document model behaviour and determine whether improvements are required and the scale of them.
