Description We study the influence of the frictional heating on the wind line-profiles of SMC stars. For this purpose we use our NLTE wind code to obtain consistent occupation numbers of studied levels and our radiative transfer code to solve the radiative transfer equation in moving media. We compare predicted wind line profiles calculated with and without frictional heating for a low-luminosity SMC star with a weak wind and discuss the relevance of frictional heating as a solution of a weak-wind problem for this star.
