The relativistic Fokker--Planck equation is solved with electron cyclotron resonance heating (ECRH) in a magnetic mirror for an assumed thermal barrier electrostatic potential profile. Two methods: a finite element technique and a Monte Carlo technique: give nearly the same results. Favorable comparison is made with recently obtained analytical expressions for the relation between axial density ratios and potential profile using parameters expected in the TMX-U and MFTF-B experiments.
