Task

Build objects for continuum kinematics, fluid motion, elasticity, transport, rheology, material response, and field-theory PDE models.

Record:

• continuum hypothesis and scale separation;
• Eulerian or Lagrangian description, coordinate frame, tensor conventions, and reference configuration;
• density, velocity, stress, strain, pressure, temperature, flux, and material parameters;
• conservation laws and closure or constitutive relations;
• compressibility, viscosity, turbulence, anisotropy, plasticity, viscoelasticity, porosity, and phase assumptions;
• geometry, interfaces, initial conditions, boundary conditions, contact, and loading;
• relevant dimensionless groups and regime boundaries;
• mesh, discretization, stabilization, convergence, residual, and conservation obligations;
• experimental material characterization and parameter uncertainty;
• pressure, rotating machinery, high-temperature, or material-hazard controls.

Do not infer continuum validity below the supported scale or promote a constitutive fit outside its calibration regime.

Return a physics-library-batch object.
