Who we serve
We work where the decision is expensive
Industry
Continuous processes, material handling, pressure equipment and support structures.
Private studies
Expert reviews, third-party design verification and technical backing for investment decisions.
Cases
Three deliveries, three decisions
Demonstration figures and fields: they show the format of a delivery, not an executed project. They are replaced by real cases with their validation before publishing.

Flow Validated DemonstrationTransfer box, concentrator plant
The model located the wear zone before assembly. The floor was redesigned and a shift stoppage avoided.

Struct Validated DemonstrationPrimary crusher support
Fatigue under cyclic loads measured on site. Two nodes were reinforced instead of replacing the structure.

Evidence
A result is reviewed, not admired
Three ways of looking at the same run. Everything that moves here is moved by you: nothing plays on its own and nothing runs ahead of the reading.
Demonstration
Demonstration figures and fields: they show the format of a delivery, not an executed project. They are replaced by real cases with their validation before publishing.
What the redesign changes
The same scale on both sides; without that a comparison compares nothing. The flat plate throws the stream against the wall, which is where wear shows up. The spoon delivers it attached to the loading point.
After 
Before How the chute fills
Six instants of the start-up transient. Steady state hides the exact moment the stream detaches, which is the one that drives the redesign.
The scale decides what you see
The same field and the same bound, three scales. Rainbow invents edges where the field is continuous and flattens the gradients that matter. Viridis and cividis are perceptually uniform and survive print and colour vision deficiency.

Rainbow and jet are banned in deliveries. Viridis for screen, cividis for print.
Method
We model what moves the decision
If the geometry does not change the result, it does not enter the mesh. Everything that does is documented.

| Control point | Simulated | Measured | Status |
|---|---|---|---|
| Discharge jet | 12.4 m/s | 12.1 m/s | ±2.5 % within criterion |
| Slurry depth | 0.42 m | 0.44 m | ±4.5 % within criterion |
| Flow per launder | 318 m³/h | 312 m³/h | ±1.9 % within criterion |
- 01 Scope We define the decision the model must support and the acceptance criterion.
- 02 Model Geometry, mesh and the minimum sufficient physics. Mesh sensitivity documented.
- 03 Convergence Residuals, balances and cut-off criteria declared before running.
- 04 Validation Checked against field measurement, testing or a published reference case.
- 05 Conclusion One page with the recommendation, its limits and what would change the answer.
Convergence, unadorned
Run residuals on a logarithmic scale. The cut-off is declared before running; what decides when to stop is the slowest curve, not the showiest one.

About us
Rigour, clarity and relevance, in that order
A Chilean multiphysics computational engineering consultancy. Bilingual delivery from the start, field experience in mining operations, and an answer with scope and schedule within 48 working hours.
To confirm
These are published once the owner confirms them against the register. Until then they do not appear on the site: a short fact sheet beats an optimistic one.
Rigour
Convergence, validation and traceability documented in every delivery. The cut-off criterion is declared before the run, not after looking at the result.
Clarity
The report explains the decision, not the method. The executive summary fits on one page; the detail, the annexes and the files go underneath.
Relevance
We model what moves the decision. If a physics does not change the answer, it is declared out of scope instead of billed.

Acceptance criterion
The criterion is agreed before the run. If the model does not reach it, we say so and the conclusion stage is not billed.
