Problem statement
- Geometry
- A small patch of 4–5 irregularly shaped (non-rectangular) elements assembled together. Exact dimensions aren't fixed — the test checks the method, not a specific geometry.
- Material
- Linear-elastic isotropic material, arbitrary E and ν (the test is invariant to the actual values).
- Boundary conditions
- Boundary nodes of the patch are given prescribed displacements matching an exact uniform strain field.
- Measured quantity
- Stress/strain at the interior nodes of the patch — must exactly reproduce the prescribed uniform field.
Script
Lands with the scripting engine (see Documentation) — this setup will be runnable from commands, no manual rebuild needed.
Results comparison
The solver core is still in development — there's no result yet. It'll appear here right after the first run, no retouching.
