ERO2.0 is a software for simulating the PWI (plasma-wall interaction) in fusion devices, in particular the erosion and material migration. The software has been initially developed at Forschungszentrum Jülich and is strongly embedded in the EUROfusion and international fusion research programme. The particular advantage is the possibility to describe the plasma-wall interaction in a fully three-dimensional (3D) approach and to calculate the impact energies and angles of particles hitting the wall with multiple geometries The simulation results can be used for important predictions concerning reactor availability (due to component lifetime, fuel retention and dust production) but also can find promising applications in plasma propulsion and plasma coating where transport model are needed.
