A generalized vertical coordinate transformation based on SPH(2) for efficient free surface flow simulations
Shujiro Fujioka, Kumpei Tsuji, Naoto Mitsume +1
We propose three new particle methods that improve computational efficiency by introducing a generalized Vertical Coordinate Transformation (VCT) for free surface flow problems wit…
Metagraph-Based Domain-Decomposed Galerkin Reduced-Order Model
Kyohei Shintate, Naoki Morita, Shigeki Kaneko +2
This study proposes a metagraph-based domain-decomposed Galerkin reduced-order model (MBDD-G-ROM) for distributed-memory parallel reduced-order analysis of large-scale problems. Th…
Domain-decomposed parallelization of B-spline based s-version of the finite element method via generalized graph abstraction
Nozomi Magome, Naoki Morita, Shigeki Kaneko +1
The s-version of the finite element method (SFEM) enables locally high-resolution analysis by superimposing independently defined finite element meshes. However, domain-decomposed…
