FEHM: Finite Element Heat and Mass Transfer Code LA-CC-2012-083 Open Source No. C13022 The numerical background of the FEHM computer code can be traced to the early 1970s when it was used to simulate geothermal and hot dry rock reservoirs. The primary use over a number of years was to assist in the understanding of flow fields and mass transport in the saturated and unsaturated zones below the potential Yucca Mountain repository. Today FEHM is used to simulate groundwater and contaminant flow and transport in deep and shallow, fractured and un-fractured porous media throughout the US DOE complex. FEHM has proved to be a valuable asset on a variety of projects of national interest including Environmental Remediation of the Nevada Test Site, the LANL Groundwater Protection Program, geologic CO2 sequestration, Enhanced Geothermal Energy (EGS) programs, Oil and Gas production, Nuclear Waste Isolation, and Arctic Permafrost. Subsurface physics has ranged from single fluid/single phase fluid flow when simulating basin scale groundwater aquifers to complex multifluid/ multi-phase fluid flow that includes phase change with boiling and condensing in applications such as unsaturated zone surrounding nuclear waste storage facility or leakage of CO2/brine through faults or wellbores. Heat Transfer DefinitionThe numerical method used in FEHM is the control volume method (CV) for fluid flow and heat transfer equations which allows FEHM to exactly enforce energy/mass conservation; while an option is available to use the finite element (FE) method for displacement equations to obtain more accurate stress calculations. In addition to these standard methods, an option to use FE for flow is available, as well as a simple Finite Difference scheme. • License FEHM is distributed as as open-source software under a BSD 3-Clause License.

Computational Fluid Flow And Heat TransferThe following are reminders for FEHM code developers using this repository. A Git workflow follows these basic steps: • Make changes to files • Add the files (‘stage’ files) • ‘Commit’ the staged files • Push the commit (containing all modified files) to the central repo • To first get the repo, run the command git clone This will download the FEHM Git repo to your current directory. • Let’s say you’ve done some editing and you’re ready to push your changes to the FEHM repository. Run the command git add file1 file2. FileN to add any files you have changed. You can also just run git add. If you want to add every changed file. • Now, run git status This gives an overview of all tracked and untracked files.
