The modern Doppler Imaging (DI) technique allows the reconstruction of
different stellar surface structures based on accurate calculation of
spectra of specific intensity. New applications like the mapping of the
magnetic field vector put very stringent requirements on the radiative
transfer (RT) solver which should be accurate, fast, and robust against
numerical errors. We describe the evaluation of three different algorithms
for our new magnetic DI code INVERS10. We also show the first results of
numerical experiments made with the new code.
