  • Chief, East Campus Integrated Program Office awarded Engineer of the Year

    Daria Van Liew, chief of the U.S. Army Corps of Engineers (USACE), Baltimore District, East Campus Integrated Program Office is the recipient of the 2021 Headquarters Lt. Gen. Elvin “Vald” Heiberg, the third, Engineer of the Year Award.

  • Sitka woman finds STEM career with Army engineers

    Everyone pursues a career in the fields of science, technology, engineering and math (STEM) for a different reason. Danielle Perkins, Department of the Army apprentice at the U.S. Army Corps of Engineers – Alaska District, followed the footsteps of her dad and grandpas into that sector.

  • U.S. Army Corps of Engineers completes Rochester Harbor east pier repairs

    The U.S. Army Corps of Engineers, Buffalo District, and its contractor, Dean Marine & Excavating, Inc., completed the $3.4 million, 600 feet of repair of the Rochester Harbor east pier, located in Rochester, New York, June 16, 2021 The section repaired is in the middle of previously repaired sections, and was close to the original construction, where the concrete cap was in poor condition and structurally degraded. Repair of the remaining approximately 400 feet of degraded reach of the east pier would be dependent upon receiving additional funding.

  • Construction begins on the Vermilion Harbor east pier

    The U.S. Army Corps of Engineers, Buffalo District, and its contractor, Kovilic Construction Company Inc., began repairs of the Vermilion Harbor east pier, located in Vermilion, Ohio, on 11 June 2021. The current $1.825 million contract was awarded on September 30, 2020. The Corps of Engineers is using available funds to repair 216 feet of the most degraded section of the Vermilion Harbor east pier. Repair of the remaining degraded reach of the east pier is dependent upon receiving additional funding.

  • New capabilities in CREATE™-AV Helios Version 11

    Abstract: CREATE™-AV Helios is a high-fidelity coupled CFD/CSD infrastructure developed by the U.S. Dept. of Defense for aeromechanics predictions of rotorcraft. This paper discusses new capabilities added to Helios version 11.0. A new fast-running reduced order aerodynamics option called ROAM has been added to enable faster-turnaround analysis. ROAM is Cartesian-based, employing an actuator line model for the rotor and an immersed boundary model for the fuselage. No near-body grid generation is required and simulations are significantly faster through a combination of larger timesteps and reduced cost per step. ROAM calculations of the JVX tiltrotor configuration give a comparably accurate download prediction to traditional body-fitted calculations with Helios, at 50X less computational cost. The unsteady wake in ROAM is not as well resolved, but wake interactions may be a less critical issue for many design considerations. The second capability discussed is the addition of six-degree-of-freedom capability to model store separation. Helios calculations of a generic wing/store/pylon case with the new 6-DOF capability are found to match identically to calculations with CREATE™-AV Kestrel, a code which has been extensively validated for store separation calculations over the past decade.

  • In situ analysis and visualization to enable better workflows with CREATE-AV™ Helio

    Abstract: The CREATE-AV™ Helios CFD simulation code has been used to accurately predict rotorcraft performance under a variety of flight conditions. The Helios package contains a suite of tools that contain almost the entire set of functionality needed for a variety of workflows. These workflows include tools customized to properly specify many in situ analysis and visualization capabilities appropriate for rotorcraft analysis. In situ is the process of computing analysis and visualization information during a simulation run before data is saved to disk. In situ has been referred to with a variety of terms including co-processing, covisualization, coviz, etc. In this paper we describe the customization of the pre-processing GUI and corresponding development of the Helios solver code-base to effectively implement in situ analysis and visualization to reduce file IO and speed up workflows for CFD analysts. We showcase how the workflow enables the wide variety of Helios users to effectively work in post-processing tools they are already familiar with as opposed to forcing them to learn new tools in order post-process in situ data extracts being produced by Helios. These data extracts include various sources of information customized to Helios, such as knowledge about the near- and off-body grids, internal surface extracts with patch information, and volumetric extracts meant for fast post-processing of data. Additionally, we demonstrate how in situ can be used by workflow automation tools to help convey information to the user that would be much more difficult when using full data dumps.

  • Corps of Engineers recognizes Dam Safety Awareness Day

    May 31st is nationally known as Dam Safety Awareness Day and the U.S. Army Corps of Engineers, Kansas City District stresses the importance of knowing, not just the benefits of dams, but also the risks of living near dams. We strive to provide the dam safety community, as well as the public, a better understanding of our efforts to reduce dam risk and promote dam safety through awareness, investment and resources to support critical infrastructure.

  • Remembering a Memphis District hero, brother

    The Memphis District and Chasteen family recently lost a beloved member to a hard-fought battle with cancer. Darian Chasteen, who most recently held the Hydraulics and Hydrology Branch Deputy Chief title, passed away on May 7, 2021. While no longer physically with us, his legacy will forever live on. Chasteen served more than 30 years with the U.S. Army Corps of Engineers, Memphis District. During that time, he made many friends and touched numerous lives. In honor of his life and the contributions he made, we take a look back at his life, happy and thankful to have known such a person.

  • Walla Walla District cost engineers provide expertise and support to FEMA and other federal agencies

    Natural disasters like floods and hurricanes can severely damage homes, businesses and infrastructure. Those who suffer damages in natural disasters can apply to FEMA for financial assistance. When this happens, a cost estimate is needed to determine how much money it would take to either repair or replace the structure in question.
