CAD Engineer for Computational Physical Sciences

Applied Research Associates, Inc.

(ARA) in Dayton, OH is seeking an independently motivated and detail-oriented engineer to create CAD models and prepare high quality surface and volumetric meshes/grids for a variety of computational physics software packages.

The unique and strict requirements of each computational package require different modeling and meshing approaches for each problem.

As such, a successful candidate must be willing to work closely with a team of computational scientists and engineers to understand the requirements of each package, and preferably learn to run some analyses.

Specific Duties Include:


* Accept CAD models in multiple formats from a variety of outside sources


* Prepare incoming models for analysis by doing some or all of the following:
+ Defeaturing
+ Surface healing
+ Boolean operations
+ Reconstruction of missing or poor-quality components


* Generate high quality meshes using multiple meshing programs based on unique requirements of different computational methods


* Write scripts to speed the process of generating meshes of many different densities for a single geometry


* Understand how CAD and mesh quality and attributes affect the ability of individual computational physics packages to compute correct results


* Occasionally reverse engineer CAD components by laser scanning or approximating components based on photographs or CT scans

Required Qualifications:


* Bachelor’s (or equivalent) with 4+ years’ experience


* 4 years’ experience with CAD


* Functional experience at least one of the following CAD/meshing software packages: Solidworks, Capstone (CREATE-Genesis), CUBIT (Sandia National Labs), Rhinoceros 3D, CATIA, Hypermesh, AutoCAD, Patran, NASTRAN, NX (Siemens), Creo (PTC)


* Ability to obtain a security clearance

 Highly Desired Qualifications:


* Bachelor’s degree in engineering, physics, computer science, or related discipline


* Active security clearance


* Knowledge of or eagerness to learn computational analysis, scripting, and other related skills
