We are seeking a Modeling and Simulation Engineer Associate to deliver FEM and FEA services to our customers at NSWC Carderock.

This role requires in-person support.

• Finite Element Modeling (FEM)
  • Prepare full ship models of Navy vessels (LHA-30 and LPD-8) for analysis to support Rough Water Trials
  • Utilize Femap and/or Hyper Mesh software to correct, refine, or un-refine 1D (beam) and 2D (shell) mesh in areas of interest and/or the entire ship in accordance with 3D product models, structural drawings, and inspections
  • Create hybrid models of each iteration of the design of BBGN(X) for Underwater Explosion (UNDEX) simulation. This process also involves Hyper Mesh and Femap, and the models will consist of 1D (beam, rigid), 2D (shell), and 0D (mass) elements
  • Modify BBGN(X) full ship models to add details such as foundations for preliminary design analysis. These detailed areas or sub-models will be all 2D (shell) elements in a nastran-compatible format, using Hyper Mesh or Femap
  • Un-refine a full ship DDG-51 Flight III model and refining the other (DDG-51) Flight models to match the intermediate mesh requirements of DPC 100-11 for future analysis
  • Refine full ship models of LSD-41 Class to match the intermediate mesh requirements of DPC 100-11 for compatibility with NLign
  • Develop, alter, modify, and update finite element models related to the analysis of the structural integrity, structural performance, and response of ships, submarines and components.
  • Assure FEM are developed in accordance with FEM guidelines specified in the requirements
  • Assure FEM passes various Quality Assurance (QA) measures specified by the TI, and when appropriate, may include at a minimum, peer review, Government review, commercial software routines and/or analysis and testing.
• Finite Element Analysis (FEA)
  • Perform FEA to assess the structural integrity; structural performance; and UNDEX response of ships, submarines and components.
  • Structural analysis includes linear and non-linear methods to evaluate stress, buckling modes, deflections, accelerations, and heat transfer

• Bachelor’s degree in Engineering related to structural analysis (Aerospace, Civil, Naval Architecture, Mechanical, or equivalent) from an ABET accredited college or university

• Two (2) years of experience with finite element analysis including advanced skills with finite element analysis software such as FEMAP.
• Experience creating and modifying shell (2D) and beam (1D) models in commercial Finite Element (FE) software, especially Femap and/or Hyper Mesh.
• Experience with ship structure in the form of drawings or 3D product models (NAVISWORKS), so that they can navigate these references as they verify or correct the FE models.
• CAD experience (such as Solid Works)

• Knowledge of structures, materials, manufacturing, ocean dynamics, or naval structural design. Familiar with naval structures…
