hydra is a collection of utilities which can be used without the need of a proper installation, however some prerequisites are needed:
- an Abaqus/Standard installation with a supported FORTRAN compiler. The present hydra version has been tested with Abaqus versions from 6.12-1 to 2017.
- a fairly recent python installation, in addition to the python version shipped with Abaqus. Currently version 2.7 or 3.6 are suggested.
For the example problems in the examples and verification
directories a README file is present, with step-by-step instructions
for executing the described analyses. These instructions are written
under the assumption that all examples are run within the example
directory itself.
- symlinks: as hydra was developed under a Unix-like (actually mostly Posix compliant) operating system, its source distribution contains symbolic links. Symlinks are fully supported only in Windows 10, see https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/. Under previous versions of Windows, symbolic links may be get substituted by a small text file containing the name of the file they are pointing to. In such cases simply copy the original file in place of the symlink.
