This article presents the results of a numerical simulation of the process of spatial positive charge accumulation in the Time Projection Chamber (TPC) of the multipurpose detector (MPD) at Nuclotron-based Ion Collider fAcility (NICA) at the Joint Institute for Nuclear Research (JINR). Based on the spatial distribution of the charges, the problem of calculating the potential of the electrostatic field created by these charges has been solved. The radial, angular, and axial distortions in the electron motions from the point of ionization to the readout planes are calculated.
