How we work, and why
Methods arrived at on real projects — analyses, custom tools and automation. No marketing overviews: every article solves one concrete problem.
Modal and harmonic analysis: when frequency decides
What modal and harmonic analysis each compute, why natural frequencies are found on a prestressed structure, and how resonances are compared relatively.
Read the article →Section properties from DXF: the torsion constant CAD leaves out
Get section properties from a DXF, including the torsion constant It, warping constant Iw, shear centre and Wpl that CAD omits — plus the polar moment trap.
Read the article →Non-linear FEA not converging: local instability or real collapse?
Reading residuals, contact elements and the stiffness curve to tell local instability from collapse — and why damping is not the first answer.
Read the article →FEA decision map: thirteen decisions before you press Solve
A tutorial shows you where the buttons are. This is about what to choose: idealisation, material, boundary conditions, stability, mesh, criterion.
Read the article →FEA basics: why the highest stress in your model may mean nothing
What an FEA solver actually computes, where meaningless stress peaks in sharp corners come from, and how to prove a result is trustworthy.
