Software Capabilities
The right tool for each analysis.
Industry-standard simulation and CAD software, plus custom solvers where off-the-shelf tools fall short. We work with your native CAD files and deliver results in formats your team already uses.

Hand Calculations
Every result checked from first principles
Software is only as good as the engineer checking it. Every simulation we deliver is backed by closed-form hand calculations, and many customers want those calculations in the stress report itself. We write them out in full: free-body diagrams, governing equations, material allowables with references, and margins of safety.
Stress analysis
- Mohr's circle & principal stresses
- Multi-axial (combined) stress
- Bending, shear & torsion
- Column buckling
- Thin- & thick-wall pressure vessels
- Elevated-temperature analysis & thermal stress
Failure & fatigue
- Maximum distortion energy (von Mises)
- Maximum normal stress (Rankine)
- Brittle Coulomb–Mohr
- Goodman criterion
- Fatigue life (S–N)
- Factors & margins of safety
Joints & fasteners
- Bolted joint analysis (preload, stiffness, separation)
- Fastener tension, shear & combined loading
- Thread stress & thread stripping
- Fastener fatigue
Fluids & thermal
- Pressure drop & flow calculations
- Valve sizing (Cv)
- Pump and system curve sizing

Electromagnetics
Magnetic and electromagnetic design
CST Studio Suite
Electromagnetic simulation of permanent magnets, magnetic circuits, coils and sensors, including magnetostatic and low-frequency field analysis.
Custom FEA solutions for magnetics
In-house finite element solvers for permanent magnet and sensor problems. They run fast parametric sweeps across magnet grade, geometry and temperature, beyond what commercial tools make practical.
CAD & Design Tools
We work in your CAD
Send native files or neutral formats such as STEP, IGES or Parasolid. We prepare simulation-ready geometry without redrawing your design, and return drawings and models in the format you use.
SOLIDWORKS
Part and assembly modeling, weldments, sheet metal, large assemblies and production drawings with GD&T.
Creo
Parametric modeling and model preparation for analysis on aerospace and defense programs.
Autodesk Inventor
Part and assembly modeling, and model exchange with Inventor-based engineering teams.
Advanced Spring Design 7
Design and verification of compression, extension, torsion and wave springs, including stress, rate and fatigue life.
