INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, ISSN: 0029-5981, DOI: 10.1002/nme.70166, Vol.126, pp.e70166-1-20, 2025 Streszczenie:
This study explores matrix-free tangent evaluations in finite-strain elasticity with the use of automatically generated code for the quadrature-point level calculations. The code generation is done via automatic differentiation (AD) with AceGen. We compare hand-written and AD-generated codes under two computing strategies: on-the-fly evaluation and caching intermediate results. The comparison reveals that the AD-generated code achieves superior performance in matrix-free computations. Słowa kluczowe:
