Finite Element Analysis

Our Finite Element Analysis (FEA) services provide accurate, simulation-driven insights to predict real-world structural, thermal, dynamic, and multi-physics behavior. We support linear and nonlinear analysis, vibration and seismic assessment, thermal and coupled-field simulations, and electromagnetic analysis using advanced commercial and open-source solvers. Our approach focuses on engineering accuracy, code compliance, and practical decision-making, helping clients reduce risk, optimize designs, and validate performance before fabrication or operation.

Frequently Asked Questions (FAQ)

What is Finite Element Analysis (FEA)?

Finite Element Analysis is a numerical simulation technique used to predict stress, deformation, vibration, thermal behavior, and multi-physics response of engineering components and systems under real operating conditions.

When is FEA mandatory according to design codes?

FEA is explicitly required or strongly recommended in codes such as ASME Section VIII Division 2, ASME B31.3 (for local stresses), API 579/ASME FFS-1, and EN 13001 for cranes.

Do regulatory authorities accept FEA-based design?

Yes. When performed correctly and documented properly, FEA is widely accepted by third-party reviewers, notified bodies, and regulatory authorities as part of Design by Analysis (DBA).

Which standards guide good FEA practice?

Good FEA practice follows guidance from ASME VIII Div 2 Part 5, ASME BPVC Annexes, API 579, Eurocodes, and industry-recommended meshing and convergence criteria.

Can FEA replace hand calculations?

FEA does not replace engineering judgment. It supplements hand calculations and is essential when geometry, loading, or material behavior is complex or nonlinear.

Is FEA required for seismic and vibration analysis?

Yes. Seismic, modal, frequency response, and fatigue evaluations commonly rely on FEA, especially for tall structures, machinery, and equipment subject to dynamic loads.

Do you provide FEA reports suitable for audits or approvals?

Yes. Our FEA reports are structured for technical review, including assumptions, code references, load cases, mesh convergence, results interpretation, and conclusions.

What types of FEA do you provide?

We provide static structural, nonlinear, modal, frequency response, thermal, coupled-field, seismic, rigid body dynamics, and electromagnetic analyses tailored to project requirements.

Which software tools do you use for FEA?

We use a combination of industry-recognized commercial tools and validated open-source solvers, selecting the most suitable platform based on accuracy, code compliance, and client needs.

Do you perform code-compliant analysis?

Yes. Our FEA work is routinely aligned with code requirements such as ASME Section VIII Division 2 (Design by Analysis), ASME B31.3, API 579/ASME FFS-1, EN 13001 (cranes), and seismic standards like ASCE 7 and Eurocode 8.

Can you handle nonlinear and large deformation problems?

Absolutely. We specialize in material nonlinearity, geometric nonlinearity, and contact nonlinearity to accurately capture real-world behavior beyond linear assumptions.

What information is required to start an FEA project?

Typically, we require geometry or drawings, material data, loading and boundary conditions, applicable design codes, and project objectives. We also assist in defining inputs if needed.

What deliverables do you provide?

Deliverables include a detailed engineering report, result plots and animations, verification checks, design recommendations, and supporting calculation files when required.

Can you support design optimization and design verification?

Yes. We support both early-stage design optimization and final design verification, including fatigue, service life assessment, and safety margin evaluation.

How do you ensure accuracy and reliability?

We follow best-practice meshing strategies, validated material models, convergence checks, and engineering judgment, combined with peer review and code-based verification.
