R&D concept screening
Compare concepts before committing to detailed design, tooling, prototype or fabrication.

Turn uncertainty into evidence.
Advanced FEA for innovators, product developers and engineering teams who need to understand behaviour before spending on the next iteration.

Where FEA creates value
Analyse the question—not just the model.
RIIS starts by defining what decision the simulation must support. Model detail, assumptions and outputs are then built around that decision.
Product development
Understand load paths, stiffness, deformation and stress to guide the next design iteration.
Prototype validation
Use simulation to identify critical zones, test assumptions and focus physical testing.
Nonlinear response
Contact, large deformation, material nonlinearity and other behaviours beyond simple linear checks.
Local stress & connections
Detailed assessment of joints, interfaces, weld regions, bolts, brackets and complex geometry.
Failure investigation
Reconstruct likely loading and response to support root-cause thinking and corrective action.
Design optimisation
Reduce weight, improve stiffness, remove hotspots and compare practical geometry changes.
Independent verification
A second technical view of modelling assumptions, boundary conditions, loads and conclusions.
R&D simulation loop
Each model should improve the next decision.
The workflow is deliberately iterative. Results are converted into practical design actions rather than left as contour plots.
01
Frame
Define the failure mode, uncertainty or comparison to be resolved.
02
Represent
Select the geometry, material, contacts, loads and constraints that matter.
03
Simulate
Run appropriate linear, nonlinear, sensitivity or comparative analyses.
04
Interpret
Separate numerical effects from meaningful engineering behaviour.
05
Iterate
Recommend the next geometry, test, material or development action.
What to send / what you receive
Start rough. Finish with a defensible recommendation.
A complete CAD model is not always required. Early engagement can begin from sketches, photographs, dimensions, load estimates or test observations.
Useful starting inputs
Problem statement, intended use, geometry, material, loads, constraints, failure evidence or test data.
Model basis
Assumptions, idealisations, boundary conditions, material model and analysis limitations.
Engineering results
Response plots, critical locations, sensitivities, comparisons and governing behaviour.
Design direction
Prioritised changes, next iteration, testing focus and unresolved risks.
Ways to engage
Use simulation at the right investment level.
The scope can grow with the maturity of the product and the confidence required.
Feasibility sprint
A focused first model to test whether the idea is viable and identify dominant behaviour.
