SANSMIC (or sansmic) is research software developed to simulate the leaching of salt caverns. Its primary use has been modeling the leaching for the caverns at the U.S. Strategic Petroleum Reserve (SPR). SANSMIC differs from other leaching software as it implements a simultaneous leach+fill simulation which was used in the 1980s during the construction and original fill of the SPR Bryan Mound site. The primary use for SANSMIC is for modeling liquid petroleum product storage caverns that use raw water for product withdrawals, and as a comparison point for newer salt disolution models.
All lower-case 'sansmic' is used as the repository name and remaining documentation to differentiate this package from the older SANSMIC program written in FORTRAN - and because all-caps feels very loud. The sansmic package provided here is a re-write of the original program using the C++ and Python programming languages.
The sansmic package requires Python 3.9 or greater and at least the numpy and pandas packages.
Installation can be accomplished most easily by using the PyPI. It can also be installed by downloading a wheel from the [releases] in this repository, or by cloning this repository and building it yourself. (Because there is C++ code at its core, building it from scratch requires a C++ compiler and the pybind11 package - but if you are building this from scratch, the authors assume you will be okay with that 😁 )
To install a pre-compiled version of sansmic, use the pip command
python -m pip install sansmic
To download and build from source, you should clone the repository (or, fork sansmic and clone your repository) and then install using the editable (-e) flag.
git clone https://github.com/sandialabs/sansmic.git
cd sansmic
python -m pip install -e .
Once installed, you can use
sansmic --help
and
sansmic-convert --help
to get help on how to run sansmic commands from the command line. For more detailed usage and API information, please see our documentation.
