How MRI radiofrequency fields heat implants and leads, why length, route and landmark matter, how ASTM F2182 and ISO/TS 10974 frame the evidence, how EMC coupling into powered devices is simulated, and where surrogates help without replacing the physics.
How a spring-driven autoinjector and a prefilled syringe load each other: drive force, stopper break-loose and glide, viscous flow through a thin needle, impact on the glass and seal contact. What a model reports, how it is validated for a stated use, and how a surrogate screens choices.
How dental implant simulation models abutment screw preload and tension-side opening, bone density and micromotion under immediate loading, jaw fixation plates and planning tools, what the ISO 14801 scope supports, and where a surrogate helps.
How orthopedic implant simulation handles hip stem fatigue, stress shielding and micromotion, what ASTM F2996 and ISO 7206-4 say about finite element models and worst-case size, how porous lattices and CT bone models change the model, and where a surrogate helps.
How heart valve simulation covers crimping, deployment into calcified non-circular roots, paravalvular leak, leaflet fatigue ranking, closure dynamics and washout, what a durability simulation can and cannot say, and how a credible model sits beside the bench tests.
How stent finite element analysis follows a stent through crimping, release into the vessel and pulsatile loading, why nitinol needs a strain-based fatigue view, what the model cannot see, and how a surrogate-assisted workflow explores the design space without replacing the durability test.
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.
