The Computational Structural Mechanics module aims to solve problems related to structures. Depending on the type of structure to solve, the user must choose between the many structural elements available. Those appearing in the GiD interface have been tested and benchmarked.
1. From GID (recommended). Go to the Data->ProblemType menu. You should see 'Kratos' with a green arrow (this arrow means you can download this problemtype). Click on Kratos and follow the instructions until the download process is completed.
2. Using svn (developers option for linux users). Download the Kratos source and compile it (LinuxInstall). After that, link the GID interface to GID by doing:
cd ln -s $HOME/kratos/gid_interface/kratos.gid /your_GID_folder/problemtypes/kratos.gid
And link the whole kratos folder to the interface:
ln -s $HOME/kratos $HOME/kratos/gid_interface/kratos.gid/kratos
Now you can update Kratos and compile it many times while the GID interface keeps linked to the newest version of the interface and the code.
