ADINA Solver Technology ADINA 해석 solver 의 성능 Overview
● Introduction
● Equilibrium Equations
● Sparse Solver
● 3-D Iterative Solver
● SMP (Shared Memory Parallel)
● DMP (Distributed Memory Parallel)
● AVX (Advanced Vector Extension)
● Memory Usage
● Idealized model discretized into finite elements
● Element stiffness matrices assembled into global stiffness matrix
● Solution of the model is the balance of internal nodal forces to external (applied) nodal forces
● Equilibrium equation: K U = F
● Solution of equations most time consuming part of the analysis
● Solver techniques: Direct or Iterative
Symmetric Sparse Solver
● Also known simply as Sparse Solver
● Direct solver - solution of equilibrium equations always obtained in a certain number of operations
● Default solver - best choice for most problems
● Run with in-core or out-of-core memory. More later in discussion on memory usage.
● Scales well with parallel processing
● May be useful in special cases where the matrix is non-symmetric
● As expected, uses more memory and computation time than symmetric sparse solver
● Only for models with Drucker-Prager, Mohr-Coulomb, user-supplied, plastic-cyclic, nonlinear elastic or DF-concrete material; large displacement Hermitian beam or alignment element
Important Tools & Techniques
▷ Enabling detailed diagnostics
- Selecting and assigning contact surfaces
- Choosing the correct elements/mesh
- Judicious use of contact compliance
- Suppressing oscillations
- Properly handling initial penetrations
- (Temporary) problem simplification
