In this work, we present the evolution of black hole - neutron star initial data produced with the new pseudo spectral code Elliptica. The code makes use of Schur complement domain decomposition method with a direct solver using cubed sphere coordinate maps and the fields are expanded using Chebyshev polynomials of the first kind. To stress the capability of the code we designed different configurations of mass ratios and spin orientations and we made use of the BAM code to evolve such initial data. Arbitrary spin magnitudes and orientations are evolved, with a maximum adimensional spin of 0.8 for the black hole and an arbitrary high spin for the neutron star.
