Jukka Aho	c5a1202c1d	chore(assemblers): comment out missing nodal_cache.jl include ... Comment out include for nodal_cache.jl as the file does not exist yet. - Comment out include("nodal_cache.jl") with TODO note	2025-12-12 23:27:50 +02:00
Jukka Aho	be8904cff5	refactor(assemblers): Update cache includes and remove old definitions ... - Added includes for coo_cache.jl, csc_cache.jl, nodal_cache.jl - Removed old COOCache, CSCCache, NodalCache definitions (now in separate files) - Removed old ElementCache, NodeCache definitions (moved to element_cache.jl) - Kept only high-level cache coordination logic	2025-11-20 16:56:36 +02:00
Jukka Aho	b78aa10602	refactor(assemblers): Implement zero-allocation cache structures ... - Implement COOCache for coordinate format assembly - Implement CSCCache for compressed sparse column assembly - Implement NodalCache for node-based assembly (future GPU) - Add reset!() methods for cache reuse in nonlinear iterations - Add extract_system() methods to get K, f from caches - Implement build_sparsity_pattern() for CSC structure pre-building - Extract mesh type parameters at runtime for capacity estimation - 407 lines of cache implementation Zero-allocation guarantee: - All arrays pre-allocated during cache creation - Assembly calls reuse existing arrays - Critical for nonlinear solvers and time stepping Memory efficiency: - COO: Triplet arrays sized for element connectivity - CSC: Pre-built sparsity pattern, reused structure - Nodal: Includes node-to-elements inverse connectivity	2025-11-18 18:02:30 +02:00
