Uncoupled Formulation

Single-phase solid mechanics

Back to Theory Overview.

Uncoupled (Single-Phase) Formulation

Use when you want a mechanically focused solve without explicit pore-pressure evolution.

Checklist

• Units and scaling are consistent (E, loads, density).
• Boundary conditions remove rigid body modes.
• Mesh is refined where gradients are expected.

Common outputs to sanity-check

• Reaction forces / equilibrium.
• Stress sign convention (compression negative, if configured that way).
• Convergence sensitivity to load stepping.
