# VCLAVIS

> VCLAVIS is a web-based software platform for pressure vessel and heat exchanger design,
> developed by a team of experienced mechanical engineers. Designed for engineering firms
> and independent engineers worldwide.

## What VCLAVIS Does

VCLAVIS enables engineers to perform pressure vessel and heat exchanger calculations in
compliance with major international codes, from any device with an internet connection.
No installation or dedicated hardware required.

Supported international design codes:

- **ASME VIII DIV1** — American standard; supports all relevant Code editions concurrently
- **EN 13445** — European standard, PED 2014/68/EU compliant
- **PD 5500** — British standard for unfired fusion welded pressure vessels
- **AD2000** — German standard; the only code allowing hand verification

## Key Capabilities

- Pressure vessel design (shells, heads, nozzles, flanges, cones)
- Heat exchanger design: shell & tube, BEM, AES configurations; Tubesheet Generator
- Stability analysis: seismic (Eurocodes / ASCE), wind, blast, acceleration, snow, live loads
- Lifting lugs, trunion, tailing lugs and rigging analysis with dynamic load factors
- Local loads analysis: WRC 537, WRC 297, PD5500, EN13445, AD2000
- Fatigue analysis per Code
- Leg, bracket, support ring, skirt and saddle support design
- Two modes: Vessel Mode (complete vessel) and Calculation Collections (individual components)
- Wizard-based input — minimal learning curve
- AI Assistant for in-app support and Code guidance (powered by OpenAI)
- Outstanding PDF calculation reports (sample reports available on site)
- Advanced material libraries
- 3D output visualization

## Competitive Advantages

- 10x efficiency boost — no hardware limits, no installations
- 30% average cost reduction vs. traditional desktop software
- 24/7 cloud access — work from any device, anywhere
- 100% up-to-date with regulatory changes
