This work aims at augmenting the ASTRA transport code capabilities of simulating magnetic confinement fusion devices. In parallel, two avenues are pursued:
First, a generic equation for the current diffusion compatible with stellarator geometry is implemented, and the code is coupled to the equilibrium solver VMEC. The equation is benchmarked against theoretical expectations and validated using experimental data from Wendelstein 7-X.
Second, a reduced XPR model, predicting XPR radiation, position, and stability, is developed and implemented in ASTRA. The model is validated against ASDEX Upgrade discharges in the Fenix flight simulator.
