The CFD modeling is conducted using THFRC’s high-speed Internet2 connection line to the Transportation Research and Analysis Computing Center (TRACC) cluster at the Argonne National Laboratory (ANL). The user interface is based on the Linux operating system. The CFD code, STARCCM+, is remotely executed at assigned computational nodes on the cluster. The computational results can then be transferred to local computers in the Hydraulics Laboratory for further data analysis.

The FHWA’s J. Sterling Jones Hydraulics Research Laboratory's numerical modeling is carried out at the Argonne National Laboratory's (ANL) Transportation Research and Analysis Computing Center (TRACC) through remote access and collaboration. TRACC studies CFD-based simulation techniques in highway hydraulics and erosion/sediment transport applications. Engineers compare these simulations to tests conducted at the hydraulics laboratory to develop and validate design formulation.
The TRACC components consists of Phoenix and Zephyr clusters and include high-performance computing, visualization, and networking systems, with 1024-core (Phoenix) and 2944 (Zephyr), customized system from Dell that comprises 128 compute nodes (Phoenix) and Atipa tech (Zephyr), each with two quad-core AMD 2378 Opteron CPUs and 8 gigabytes of RAM (Phoenix), two 16-core AMD 6273 and 32 gigabytes of RAM (Zephyr), a DataDirect Networks storage system consisting of 180 terabytes of shared RAID storage (Phoenix) and 120 terabytes (Zephyr), and a high-bandwidth, low-latency InfiniBand network for computations. Available software packages include: ANSYS FLUENT, HyperMesh, LS-DYNA®, LS-OPT®, MADYMO, MATLAB, NoMachine, STAR-CD, STAR-CCM+, STAR-Design, and TRANSIMS.
Training on the CFD software is conducted every year. Lectures and tutorial-based drills are offered during the training to onsite and remote participants. TRACC staff works with TFHRC users to identify the most useful topics to include in the training courses.
