Chasing a melt pool
The moving heat source behind welding and 3D-printed metal: a travelling melt pool with a comet tail of heat. Solved on physicsbase's transient field engine and checked against Rosenthal's classic solution.

A crack inside the mesh
The eXtended Finite Element Method on physicsbase: a crack that cuts straight through elements, no remeshing. K₁ recovered from the energy release rate — within 1.5% of the handbook.
Growing a crack from scratch
Two physics in a loop: the single-edge-notched fracture benchmark, coupling physicsbase's structural and field solvers to watch a crack propagate on its own.
Letting the structure design itself
The classic SIMP topology-optimization method on the engine — an FE solve wrapped in an optimization loop. The iconic optimized cantilever, with the complete code.
One kernel, many physics
How a single scalar-field solver does heat conduction, mass diffusion, potential flow, and transport — and why they're all the same equation wearing different labels.
How we test a physics engine
Every element and analysis is checked against a closed-form answer — the test suite is the spec. A tour of the 59 validations that keep the engine honest.
