The OLTRION engineering team runs CFD, FEA and multiphysics simulation programmes for aerospace, automotive, energy and industrial clients, and builds the machine-learning tools that speed them up. These articles come from that project work.

How seat transmissibility and the SEAT value are defined, why a SEAT value below one can still amplify the frequency your road supplies, how foam, suspension and occupant apparent mass set the curve, and how a simulation workflow tests a seat before the shaker.
How heat, moisture and air move through a heated and ventilated car seat, how a thermo-physiological manikin turns that into local skin temperature and sensation, what an open EV test says about warm-up energy, and how a simulation workflow tests a layout before you build it.
How seat foam hardness differs from the compression curve a model needs, how foam is calibrated from compression tests, what meat-to-metal simulation adds with the cover and frame, and how a surrogate screens foam and suspension changes without claiming to rate comfort.
How aircraft seat crash simulation reproduces the 14 g and 16 g dynamic conditions of 14 CFR 25.562 and CS 25.562, why the stiffness window and the pre-deformed floor make it hard, what FAA AC 20-146A asks of a validated model, and where AI helps without replacing the physical tests.
How a rear impact loads the neck, what Euro NCAP, IIHS and FMVSS 202a measure, how a BioRID-type dummy model is verified and validated, and how a surrogate with a stated range tunes backset and recliner yield around your explicit solver.
How post weld heat treatment relieves weld residual stress by yield-strength drop and creep, why thick sections and local heating bands are hard, how much stress remains for fracture and fatigue assessment, and how a simulation workflow tests a cycle before you run it.
How to simulate brazing: capillary fill and the joint gap at temperature, furnace temperature uniformity, thermal-expansion mismatch in dissimilar-metal and ceramic-metal joints, residual stress after cooling, and surrogate-assisted screening of trial loads.
How to simulate rotary, linear and friction stir welding: heat from friction and plastic work, flash and material flow with ALE, Eulerian and particle methods, process windows, dissimilar-metal joints, residual stress, and AI surrogates with stated limits.
How to simulate laser and electron beam welds: conduction and keyhole mode, equivalent heat sources versus melt-pool CFD, thin-wall distortion with clamping, joint-gap sensitivity, why FEA does not predict porosity, and surrogate-assisted fit-up screening.
Have a model that will not converge?
Send the geometry, the physics and the decision it has to support. We answer with an approach, not a sales call.
