# simnibs.simulation.tdcs_neumann¶

simnibs.simulation.tdcs_neumann(mesh, cond, currents, electrode_surface_tags)

Simulates a tDCS electric potential using Neumann boundary conditions on the electrodes

Parameters
• mesh (simnibs.msh.mesh_io.Msh) – Mesh file with geometry information

• cond (simnibs.msh.mesh_io.ElementData) – An ElementData field with conductivity information

• currents (list or ndarray) – A list of currents going though each electrode

• electrode_surface_tags (list) – A list of the indices of the surfaces where the dirichlet BC is to be applied

Returns

potential – Total electric potential

Return type
