Autonomous Undersea Vehicle (AUV) Structural FEA Models
For three years I was the lead engineering analyst at Bluefin Robotics, a leading AUV & Remotely Operated Vehicle (ROV) manufacturer. All engineering design was done with the SolidWorks 3D solid modeler. Engineering analysis was conducted with SolidWorks Simulation Premium FEA, and Autodesk Simulation Mechanical FEA for many stress and dynamic analyses on AUV's, ROV's, lift & tow assemblies, and docking stations. These AUV's are "wet" vehicles with seawater entrained inside and interior watertight and pressure resistant housings for specific operational and payload modules. Typical payloads include sophisticated sonar systems and/or video and still cameras. Numerous Mathcad and Excel computations were carried out to determine loads, bending moments, shear forces, and boundary conditions. Weld analyses and bolted joint analyses were also conducted via Mathcad, Excel, and FEA model interpretation. I was their internal expert on weld analysis, and composite analysis & design.

Wet Electrostatic Precipitator Thermal FEA Models
These results are from quarter symmetry 3D Nastran FEA plate element models of
a wet electrostatic precipitator which is used to remove particulate fly ash
from industrial smoke stacks. Ten FEA analyses were conducted for steady state
temperature, thermal strain, thermal stress, buckling, and structural stress
for different thermal loads, and boundary conditions. Numerous Mathcad
documents and Excel spreadsheets were developed to define both forced
convection and natural convection fluid dynamic and thermodynamic boundary
conditions. Once the thermal problems were defined, DeepSoft, LLC. developed
an innovative hanger solution that allowed the client to solve severe
thermal stress and buckling problems they were having during abnormal operating
conditions. Analyses were conducted with: Femap, Nastran, Mathcad, and
Excel.

FEA-CAE-Engineering.com is the Finite Element Analysis (FEA) & Computer Aided Engineering (CAE) specific website for DeepSoft, LLC. an independent consulting engineering firm specializing in engineering analysis, ocean & mechanical engineering design, and virtual product development. DeepSoft, LLC. utilizes state of the art FEA & CAE engineering software tools coupled with over thirty years of engineering analysis and design experience to help you solve engineering and manufacturing problems. DeepSoft, LLC. has performed stress, thermal, and dynamic analyses with NEi Nastran / Femap as well as Autodesk Simulation Mechanical / Algor on many projects as well as mechanical design with leading edge 3D solid modelers such as Inventor, SolidWorks, & SpaceClaim.
We want to become your FEA & CAE online resource, whether working locally or remotely on your applications. DeepSoft, LLC. can assist you in making the transition from working in 2D to doing everything in 3D. 3D solid model based CAE & FEA tools are very powerful but have significant learning curves. We have been working with both of these technologies for many decades and can either do the work for you or assist your staff in performing the work in house.

DeepSoft, LLC. is an independent consulting engineering firm that assists clients in developing new products, evaluating or redesigning existing products, analyzing failures, or who require engineering analysis services. We provide answers to complex questions using state of the art engineering software tools like Femap, Nastran, Autodesk Simulation Mechanical / Algor, for stress, thermal, and dynamic FEA. Complex 3D solid and surface models can be created with Inventor Professional, or SolidWorks for new designs. Existing product designs can be converted from older legacy CAD tools to Inventor Professional, or SolidWorks.
For virtual product development, we can accept (or create) 3D solid or surface geometry in Inventor, or SolidWorks native formats as well as all neutral file formats: IGES, STEP, ACIS, and Parasolid. This capability is essential for analysts who only want to see a structurally significant model not all of the minute detail required by a design engineer.
Ted K. Fryberger, PE, the principal of DeepSoft, LLC, has over thirty years of engineering analysis and design experience in the defense, manufacturing, material handling, nuclear waste, environmental, oceanographic, and electronics industries. This experience has included a wide range of product types including: manufacturing machinery, hoists, diving and deep submergence equipment, US Navy's standard missile, US Army's portable ultrasonic cleaner, US Navy's ASDS submersible, nuclear waste vitrification melters, printed circuit boards, wet electrostatic precipitators, and new product development.
I have extensive experience using CAE & FEA software - I began using AutoCAD in 1984; Algor FEA in 1988; 3D solid modelers (Mechanical Desktop & Inventor) in 1999; Femap & NEi Nastran, Algor Nonlinear, and Fatigue Wizard in 2004; SolidWorks Simulation Premium in 2013; Autodesk Simulation Mechanical (subsumed & upgraded Algor & NEi Nastran) and AutoCAD CFD in 2014. I began programming in C in 1984, and C++ in 1991.
