CoREAS simulation for the GRAND project — •Chao Zhang, Tim Huege, Tanguy Pierog, Markus Roth, Andreas Haungs, Frank Schroeder, and Ralph Engel — Institut fuer Astroteilchenphysik, Karlsruher Institut fuer Technologie-Campus Nord, Post-fach 3640, 76021 Karlsruhe, Germany

The GRAND project starts deploying antennas this year, which will give birth to its first stage, GP300 with 300 antennas in the near future. A new version of CORSIKA7 has been adapted and validated to simulate upward-going air showers for radio detection which will be the main detection channel in this project. A library of air showers is made with CoREAS by applying the best knowledge of GRAND including the atmospheric model and magnetic field of the site. A detailed analysis of the new patterns induced by inclined air showers leads to a better understanding of the scenario of their radio emission from higher to lower air density.
