Module primitives 

Layer 1a — dimensionless scalar constants and the tensor-algebra primitives (Vector3, Tensor, SymmTensor, SphericalTensor). Layer 1a — the primitive numeric types OpenFOAM builds everything on.

This module holds the dimensionless scalar type and small-/large-number constants (scalar) together with the fixed-size 3-D tensor-algebra primitives: a 3-vector (Vector3), a full 3×3 tensor (Tensor), a symmetric 3×3 tensor (SymmTensor), and an isotropic diagonal tensor (SphericalTensor). All components are plain f64 (dimensionless SI); uom-dimensioned quantities are layered on top elsewhere in the crate. Each type mirrors its Foam:: counterpart, including component storage order and the OpenFOAM operator conventions (&, &&, ^, *).

Modules

eigen

The scalar floating-point type and the small/large numeric constants. Spectral decomposition of 3x3 tensors – eigenvalues, eigenvectors, and the basis every isotropic tensor function (logarithm, exponential, square root) is built on. Eigenvalues and eigenvectors of 3x3 tensors.

scalar

The scalar floating-point type and OpenFOAM’s small/large numeric guard constants.

spherical_tensor

Isotropic diagonal tensor ii * I (SphericalTensor). Isotropic diagonal tensor (SphericalTensor) — an OpenFOAM primitive that stores only the single scalar ii of ii * I.

symm_tensor

Symmetric 3×3 tensor (SymmTensor). Symmetric 3×3 tensor (SymmTensor) and its OpenFOAM-style operators.

tensor

Full (non-symmetric) 3×3 tensor (Tensor). Full (non-symmetric) 3×3 tensor (Tensor) and its OpenFOAM-style operators, invariants, and decompositions.

vector

3-component vector (Vector3). 3-component vector (Vector3) and its OpenFOAM-style operators.
