01 / WHEN YOU NEED IT

Questions this analysis answers.

Structural analysis is worth paying for when a wrong answer is expensive: a rejected approval, a field failure, or an over-designed part you build a thousand times.

Every project starts from the decision you need to make — the analysis type follows from it.

Q1Will it carry the design loads with the required safety margin?→ Static analysis + code check
Q2Can we remove material without losing capacity?→ Parametric study / optimisation
Q3Why did it crack — and will the fix work?→ Root-cause FEA + fatigue
Q4How many cycles will this welded detail survive?→ Fatigue (S-N), EN 1993-1-9
Q5Will this slender member or thin panel buckle?→ Linear & nonlinear buckling
Q6Will the approver accept our own calculation?→ Third-party review

02 / DELIVERABLES

What you receive. In writing, before we start.

Each item is listed in the scope document you sign off. Nothing on this list is a surprise at the end.

Results review meeting

A walk-through with your engineers. Questions answered and recorded in the final revision.

Revision round

Re-run for design changes within the agreed scope, with a revision log in the report.

03 / METHODS

The right analysis for the question — not the most expensive one.

The mesh is refined only where the gradients are. Accuracy where it decides the answer, speed everywhere else.

INCOMPLETE DATA?Most projects start that way.We list what's missing in the scoping call. Anything we have to assume is recorded in the report's assumption register — never hidden in the model.

06 / THE REPORT

10 / FAQ

Asked before every project.

Something else? Ask it in the problem statement — the answer comes with the scope.

Which software do you use?

Tessera — the solver we build — runs the free calculators on this site today, each published with its reference cases. For project work the solver is chosen against the standard the result must satisfy, and named in the written scope. Every report states the solver, version and element types, so the result can be reproduced independently.

Can you work under our NDA?

Yes — we sign yours or provide ours before any file is exchanged.

Our data is incomplete. Can we still start?

Usually, yes. Missing inputs are listed in scoping, and every assumption we make is recorded in the report.

Do you sign or stamp designs?

Yes. All engineers responsible for the relevant engineering disciplines hold the appropriate professional qualifications and are duly authorized to sign and stamp engineering designs within their respective areas of competence.

How is the price set?

Per written scope: geometry complexity, number of load cases, and whether nonlinear or fatigue analysis is needed.

What if the design fails the check?

Following the analysis, any areas that do not meet the applicable acceptance criteria, together with the corresponding safety margins and required design improvements, will be clearly documented with their technical justification. Following implementation of the recommended design modifications, one re-analysis of the revised design for verification purposes is included within the scope of services and the quoted price.
