Sequential and fully coupled

Our thermo-structural FEA simulation services couple heat transfer and structural mechanics in a single analysis. This gives engineering teams a clear picture of thermal hotspots, thermally induced stress, and expansion mismatches before any prototype is built. Widely used for electronics enclosures, engine components, and pressure vessels across aerospace, automotive, and energy sectors.

• Steady-state and transient thermal FEA
• Thermal-structural coupling (sequential and fully coupled)
• Thermoelastic stress and thermal fatigue analysis
• Electronics and PCB thermal-structural validation
• Thermal expansion and joint mismatch analysis
• Refractory and high-temperature component simulation

Modal, harmonic and random

Our FEA consulting services for NVH analysis cover modal, harmonic response, random vibration, and acoustic-structural coupling. We identify resonance risks and dynamic failure modes early in the design cycle, helping automotive, industrial, and aerospace clients reduce noise and improve structural durability.

• Free and constrained modal analysis (frequencies and mode shapes)
• Harmonic response and frequency sweep analysis
• Random vibration analysis (PSD loading)
• Response spectrum analysis (seismic and shock)
• Acoustic-structural coupling for radiated noise prediction
• Rotating machinery critical speed and whirl analysis

Lightweighting and design refinement

This is the most advanced layer of our finite element analysis services. Sub-modeling gives high-resolution stress results on critical regions without the cost of refining a full model. Topology optimization then removes non-load-bearing material systematically, producing lighter and stiffer designs ready for additive manufacturing and casting workflows.

• Global-to-local sub-modeling for critical stress regions
• Topology optimization for lightweighting (AM and casting)
• Shape and size parametric optimization
• Design of Experiments (DOE) and surrogate model FEA
• Sensitivity analysis and design variable ranking
• Adjoint-based structural shape optimization
