The U.S. Department of Energy (USDOE) Office of Environmental Management (EM), Office of Soil and Groundwater Remediation, is supporting development of the Advanced Simulation Capability for Environmental Management (ASCEM). ASCEM is an open source and modular computing framework that incorporates new advances and tools for predicting contaminant fate and transport in natural and engineered systems. ASCEM is designed to integrate modeling tools under one framework. It is designed to facilitate integrated approaches to modeling and site characterization, and provide robust and standardized assessments of performance and risk for EM cleanup and closure activities. It is linked with applied field research sites funded by EM.

The ASCEM project has continued development of capabilities, with emphasis on both the Platform and Integrated Toolsets and High-Performance Computing (HPC) multiprocess simulator. The Platform capabilities provide the user interface and tools for end-to-end model development, starting with definition of the conceptual model, management of data for model input, sensitivity analysis, model calibration and uncertainty analysis, and processing of model output, including visualization. The HPC capabilities target increased functionality of process representations, toolsets for interaction with Platform, and verification and model confidence building.

In the fall of 2013, ASCEM will publically release the basic R&D version of the code. The “User Release” will consists of a description of the software capabilities, a downloadable version of the toolsets with accompanying input files, and tutorials based on select test cases. Outreach efforts consisting of direct user interactions will completed along with a series of workshops in 2014. Continued enhancement of the ASCEM family of codes will also occur in 2014. Development efforts will include enhancing geochemistry and reactive transport capabilities for the HPC simulator and adding both risk and decision support to the Platform. This presentation will describe specifics of the release as well as the test cases and initial feedback.
