We produced a model grid of rotating main and post-main sequence starswith the Geneva Stellar Evolution Code (GENEC). The initial chemicalcomposition is tailored to compare with observations of early OB typestars in the Large Magellanic Cloud (LMC) and the grid covers stellarmasses in the range of 7 <= M/M sun <= 15 and initialvelocity between 0 km s-1 <= v sin(i) <= 300 kms-1. The model grid has been used to determine the changes inthe surface Nitrogen abundances during the star evolution and theresults have been compared with observations.
