I have been currently working on an slender body(Missile) external aerodynamics problem and my guide has asked me to perform the same using SU2, since I am new to this software i am having some issue regarding the execution, its been more than 4 weeks since i am stuck, need some help to resolve it.
This is the geometry and when I am running it on SU2 i am geting the following error messages. ------------------------------------------------------------------------- | ___ _ _ ___ | | / __| | | |_ ) Release 8.0.1 "Harrier" | | \__ \ |_| |/ / | | |___/\___//___| Suite (Computational Fluid Dynamics Code) | | | ------------------------------------------------------------------------- | SU2 Project Website: https://su2code.github.io | | | | The SU2 Project is maintained by the SU2 Foundation | | (http://su2foundation.org) | ------------------------------------------------------------------------- | Copyright 2012-2024, SU2 Contributors | | | | SU2 is free software; you can redistribute it and/or | | modify it under the terms of the GNU Lesser General Public | | License as published by the Free Software Foundation; either | | version 2.1 of the License, or (at your option) any later version. | | | | SU2 is distributed in the hope that it will be useful, | | but WITHOUT ANY WARRANTY; without even the implied warranty of | | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
