HiFEM is available for free to all Sandia employees. Contact Chester “Chet” Weiss, cjweiss@sandia.gov, for access.
All other users will need to have a license. If you do not already have a license, please contact ip@sandia.gov. No cost licenses are available to U.S. Government Agencies (i.e. military, government labs and/or agencies) and companies performing work under an active contract issued directly by a U.S. Government entity. Fee-bearing licenses may be available to all other commercial entities.
Once a request is submitted, a HiFEM® licensing liaison will initiate the approval process. Assuming no additional information is required for the request, a license agreement will be sent via email for review and signature, if required. Please note, it can take a few weeks to process your request.

| Package | Record Number | Description |
| HFEM3D v.1.0 | 2238 | This software solves the three-dimensional Poisson equation div(k(grad(u)) = f, by the finite element method for the case when material properties, k, are distributed over hierarchy of edges, facets and tetrahedra in the finite element mesh. Method is described in Weiss, C.J. (2017). Finite element analysis for model parameters distributed on a hierarchy of geometric simplices. Geophysics, v82, E155-167, doi:10.1190/GEO2017-0058.1 |
| inp2cjw | 2627 | Utility program for hierarchical finite element analysis which converts Abaqus formatted (inp) model output from Cubit to a format (cjw) for HFEM and HFEM-Hydro modeling codes while also introducing volume, facet and edge material properties into the model. Version 1.1: added flag ‘-w’ to generate output for Whitney edge elements. |
| Linv_hfem3d | 2827 | The Linv_hfem3d software is used to invert geophysical electrical (E) field data for automated well integrity monitoring with affordable computational cost. The software employs hierarchical 3D geo-electrical models to reduce the insignificant dimensions of well casings in the forward problem and the Levenberg-Marquart nonlinear least squares algorithm in the inverse problem. The computational meshes of hierarchical geo-electrical models are generated by using Cubit. The sensitivities of model parameters are automatically distributed across processors of parallel cluster at each iteration for computational efficiency. Assuming time-invariant host geologic medium, the software predicts the state of the well integrity based on changes in the E field. |
| hifem_transport | 2828 | The hifem_transport software is used to simulate transport processes in large geologic environments consisting of complex fractures and man-made infrastructures with affordable computational cost and mesh refinement. The code solves the advection-dispersion equation in the Laplace domain. The Earth models with such complex model features can be designed by considering the reduction of insignificant dimensions of fractures/infrastructures and embracing their corresponding hierarchical material properties, and their computational meshes are generated by using Cubit. The finite element solutions are automatically distributed across nodes of parallel cluster for efficient computation of advection and dispersion in geologic media. The software allows to import Darcian velocity fields of fractures and to employ time-dependent source types and boundary conditions. |
| HiTEM | 3185 | The HiTEM3d v1.0 software is used to simulate transient electromagnetic diffusion in large geologic environments consisting of highly-conductive wellbore systems with affordable computational cost and mesh refinement. The Earth models with such complex model features can be designed by considering the reduction of insignificant dimensions of wellbores and embracing their corresponding hierarchical material properties, and their computational meshes are generated by using Cubit. The finite element solutions are automatically distributed across nodes of parallel cluster for efficient computation of transient electromagnetic fields in geologic media. |
| hydro-hifem v.1.1 | 2551 | The hydro-hifem 1.0 software is used to simulate transient physical processes in large geologic environments consisting of complex fractures and man-made infrastructures with affordable computational cost and mesh refinement. The Earth models with such complex model features can be designed by considering the reduction of insignificant dimensions of fractures/infrastructures and embracing their corresponding hierarchical material properties, and their computational meshes are generated by using Cubit. The finite element solutions are automatically distributed across nodes of parallel cluster for efficient computation of transient fluid flow or heat conduction in geologic media. |
