Preissner Engineering & Consulting, LLC is an Ann Arbor, Michigan-based engineering consulting company. We have expertise in mechanical systems and structural design, advanced finite element analysis (FEA), 3D computer-aided design (CAD), computational fluid dynamics (CFD), and test data acquisition (DAQ). We provide innovative analysis and design solutions to companies and organizations in high-tech industries including defense, aerospace, transportation, energy, infrastructure, and others.

Transporter for James Webb Space Telescope getting taken off aircraft at arrival locationFinite Element Analysis (FEA):  Our experience with FEA includes everything from basic modeling and static analysis to complex assemblies with dynamic, vibration, contact, nonlinear, and fatigue effects. We can analyze metallic, non-metallic, and composite materials. We use our data acquisition system to verify physical components and validate our analyses.

Computational Fluid Dynamics (CFD):  With CFD we are capable of a full range of analysis types, up to and including transient, compressible, and multi-phase flow with all types of boundary conditions, heat transfer, and both internal and external flow paths.

Computer Aided Design (CAD):  In 3D design we use our CAD tools from the beginning of a project in exploring the design space, until the end for producing finished drawings for communication and production.

PEC can tackle projects of any size, from initial R&D explorations to multi-company, multi-agency systems. Companies use our services to develop new products, improve current designs, and assess legacy system performance and/or failure. We embrace a philosophy of total quality as well as quality improvement in all aspects of our business. PEC is NIST 800-171 compliant.
