The GPU implementation by means of the OpenACC technology of the simulation of the current distribution in tungsten sample is heated by an electron beam pulse is presented. A special case of axial symmetry without taking into account electrical driving forces is considered. The temperature in the sample, calculated from the two-phase Stefan problem, is needed to solve the electrodynamic equations. The calculation time for different GPUs compared to CPU time is given. © 2021 Institute of Physics Publishing. All rights reserved.
