Matrix-free methods for finite-strain elasticityWichrowski, Michał (Avtor) Rezaee-Hajidehi, Mohsen (Avtor) Korelc, Jože (Avtor) Kronbichler, Martin (Avtor) Stupkiewicz, Stanisław (Avtor) automatic differentiationcode generationfinite elementsfinite-strain elasticityhigh-performance computingmatrix-freeThis 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.20252026-03-11 11:00:09Članek v reviji180562UDK: 519.62:004.94ISSN pri članku: 1097-0207DOI: 10.1002/nme.70166COBISS_ID: 271239427sl
