Finite element analysis
See the stress before the steel does.
Dipta Design and Engineering LLP runs finite element analysis on your parts, assemblies and pressure equipment — structural, thermal, modal and buckling — and tells you in plain numbers where they will fail, and what to change before you cut metal.

It answersWill it yield, and how far will it deflect under the worst load?
We needCAD, material, the loads, and how the part is bolted or welded.
You receiveStress and deflection plots, with a margin of safety at every hot spot.
It answersWhich frequencies make it ring — and are they near your motor, pump or road input?
We needCAD, material, attached masses and the operating speed range.
You receiveNatural frequencies, animated mode shapes and ways to stiffen it.
It answersWhere does heat build up, and how hot does it get in service?
We needPower dissipated, ambient temperature, and airflow or cooling data.
You receiveA temperature map, hot-spot temperatures, and thermal stress if it matters.
It answersAt what load does a column, strut or thin wall suddenly give way?
We needCAD, material, the load path and how the ends are held.
You receiveCritical load factors, buckled shapes and where bracing helps most.

02 / Nozzle Analysis
Submit the nozzle. Get the report.
The portal takes a nozzle’s geometry, materials, design conditions and piping loads, solves the elastic-plastic model on our own solver and returns a complete assessment report — the same analysis we do by hand, made repeatable and priced up front.
- 01Enter the nozzle on the dashboardBase component, neck, flange, loads and materials from the design-code tables, with a dimension sketch beside every field. Pre-flight checks flag anything unusual before you submit.
- 02See the price before you submitJobs are paid in credits from your account; the quote is shown on the form and nothing is charged until you confirm.
- 03We solve itA three-dimensional elastic-plastic finite element model, two load cases, mesh sensitivity and equilibrium checks — run by our engineers on our own solver, not in a browser.
- 04Download the reportThe model, materials, loads, results, verdicts and a compliance matrix against the design code’s documentation requirements. Your files stay available on the portal.

Accounts are opened by us for companies we work with. Sign in to submit a nozzle, follow progress and download reports.
- Shells, 2:1 ellipsoidal heads, cones and blind flanges
- Pipe necks, self-reinforced forgings and long weld necks
- Reinforcing pads, eccentric and hillside nozzles
- Load factors per the design code and division you specify
- Report issued under the code edition in force
03 / Process
From CAD file to a clear decision.
- Step 01
Brief
You send the CAD, the material and the load cases. We agree the exact question the analysis has to answer.
- Step 02
Geometry & mesh
We clean up the geometry, then refine the mesh at fillets, holes and contacts until the results stop changing.
- Step 03
Loads & supports
Boundary conditions are modelled on how the part is really bolted, welded and loaded in service.
- Step 04
Solve & check
We solve, then cross-check the peak results against hand calculations before anything leaves the office.
- Step 05
Report
Contour plots, margins of safety and specific design changes, walked through with your engineers.
04 / Deliverables
A report your engineers can act on.
- 01Contour plotsStress, deformation and temperature for every load case, with hot spots called out.
- 02Margins of safetyPeak results checked against your material’s allowables, location by location.
- 03Convergence evidenceMesh studies showing the numbers won’t move with a finer mesh.
- 04Design recommendationsWhere to add material and where to take it away, ranked by effect.
- 05Model filesSolver files and full-resolution images on request, for your own records.
05 / Contact
Send us the part you’re worried about.
Tell us what you are working on — a nozzle to assess, a part to analyse, a vessel to design, a report to review. Share the CAD, the material and how it’s loaded, and we’ll come back with a scope, a timeline and a quote at the e-mail address or phone number you give.
