Jukka Aho	e9b039509c	feat(fields): Add field variable API with Displacement, Temperature, and DisplacementRotation ... Create src/fields/api.jl defining field-specific abstractions: - AbstractField base type for all field variables - Displacement{Dim} for solid mechanics (Dim DOFs per node: ux, uy, uz) - Temperature for heat transfer (1 DOF per node: T) - DisplacementRotation{Dim} for beams/shells (2*Dim DOFs: displacement + rotation) - dofs_per_node() interface for DOF counting Field type determines solution vector structure, boundary condition interpretation, and assembly dispatch. Examples: - Displacement{3} with ContinuumFormulation{FullThreeD} → 3D elasticity - Temperature with ContinuumFormulation{FullThreeD} → heat transfer - DisplacementRotation{3} with BeamFormulation → 6 DOFs (3 trans + 3 rot) Part of systematic modular API architecture.	2025-11-15 18:40:05 +02:00
Jukka Aho	73ec910589	feat: Consolidate FEMBase.jl into JuliaFEM (Phase 1 complete) ... MAJOR MILESTONE: FEMBase + FEMBasis fully consolidated, JuliaFEM loads! Consolidated files: - src/elements/ (3 files): elements.jl, elements_lagrange.jl, integrate.jl - src/fields/ (1 file): fields.jl (DCTI, DVTI, DCTV, DVTV, etc.) - src/sparse/ (1 file): sparse.jl (SparseMatrixCOO, SparseVectorCOO) - src/assembly/ (2 files): problems.jl, assembly.jl - src/solvers/ (1 file): solvers_base.jl - src/analysis.jl, src/core_types.jl (Node, IP, IntegrationPoint) Changes to JuliaFEM.jl: - Added dependencies: Tensors, Calculus - Removed @reexport using FEMBase (now consolidated) - Added 20+ include statements for consolidated files - Include order: fields → core_types → fembase_compat → sparse → elements Compatibility layer: - Created fembase_compat.jl: Minimal FEMBase submodule for vendor packages - Temporarily disabled vendor-specific Mortar2D functions in solvers_modal.jl Bug fixes: - Changed i == 1 → isequal(i, 1) in integrate.jl (== operator overridden by fields) - Resolved all FEMBasis. namespace references throughout codebase Result: - ✅ JuliaFEM loads successfully on Julia 1.12.1 - ✅ 134 exported symbols (was 171 with separate FEMBase) - ✅ Core types accessible: Seg2, Quad4, Problem, AbstractProblem, etc. - ⚠️ Vendor packages show FEMBase cache warnings (expected, harmless) TODO: - Re-enable Mortar2D functions after vendor consolidation - Field system == operator override needs redesign (Phase 4) - Continue Phase 2: Consolidate remaining vendor packages	2025-11-08 09:39:16 +02:00
