From CFD to thermo-structural analysis: engineering across physics domains
Studies across flow, heat transfer, combustion, structural analysis and validation. Every case opens at full size.
The value is not one contour, but a connected interpretation of the nozzle, mixing region and diffuser.
Species fields become useful when they can be connected to geometry, feed conditions and a concrete design decision.
The transient plume is treated as a dedicated nozzle problem: jet-core formation, recirculation and downstream development.

Discuss your engineering project03 / Your briefNOT A MENU ITEM — AN ENGINEERING QUESTION
We start with the decision you need to make
The problem may be anything: a new design, unstable operation, excessive pressure loss, overheating, mixing, phase change, model verification or a comparative study. The physics and methodology are selected around the project objective.
Understand what is happening inside
Jets, recirculation, temperature, species, pressure or interfaces — only the fields that answer your question.
Compare alternatives before fabrication
Geometry, operating regime, flow rate, thermal load, feed arrangement or another design variable.
Establish whether the model can be trusted
Convergence, balances, mesh sensitivity and comparison with experimental or operating data.
Get a conclusion suitable for a technical decision
Not a collection of images, but a cause-and-effect argument: what matters, how much, and which option is more defensible.
04 / SIMULATION VIDEO STUDIESCFD · MULTIPHASE · STATIC STRUCTURAL
Dynamic process evidence when one frame is not enough
These sequences show how flow, phase change, jet development, multiphase behaviour and structural response evolve over time. The purpose is to reveal the dynamics behind performance — not just a single static frame.
