We have adapted the EMC3‐EIRENE code for modeling of a linear divertor plasma simulator in order to demonstrate plasma‐wall interactions with three‐dimensional (3D) effects. 3D distributions of hydrogen plasma and neutrals can be successfully calculated for four different types of target plates: a V‐shaped target, inclined targets with open and closed structures, and a planer target. Hydrogen atoms and molecules are accumulated more effectively in the V‐shaped target plate, leading to a higher electron density with lower electron temperature than the planar target plate.
