Rigid or Flexible Multibody Simulation — and How to Tell
At the start of every multibody simulation stands a decision that governs how meaningful the whole model will be: rigid or flexible bodies? Get it wrong and you get forces that are either needlessly expensive or simply wrong. Yet the questio...
Why the Perfect Model Is the Unsafe One in Buckling Analysis
It sounds paradoxical: a perfectly modelled component can produce a dangerously optimistic result in a buckling analysis. Calculate a thin-walled structure without imperfections and you get a buckling load the real component never reache...
Cw or Cd? When Flow Coefficients Trip over Translation
Anyone documenting a CFD analysis while switching between German and English technical language can overlook an awkward trap: the same physical quantity is named differently in each language — and transferring the coefficients by their letters...
Does Your Pressure Equipment Need a Code Verification?
Anyone placing pressure equipment on the market eventually faces the same question: is a sound design to good engineering practice enough, or do you need a formal, verifiable strength verification to a harmonised code? The answer drives effort...
Stability or Operability — Which Seismic Verification Do You Need?
People often speak of "the seismic verification" as if it were one thing. In fact there are two fundamentally different verifications — and confusing them is expensive. One allows the component to deform permanently. The other requ...
