ANSYS Iterative Advantage • Powersolver has a proprietary and robust preconditioner – Parallel matrix/vector multiply – Wide usage, robust • Many additional iterative solvers for complex systems, non-symmetric, etc. • New high performance parallel solvers – AMG Algebraic Multigrid – DDS Domain Decomposition Solver

06.08.2018 · Iterative solver uses a "guess and check" type of algorithm and the "residual" is a measure of closeness between the approximate (guessed) and exact solution. Details of the iterative solver method are found in the HFSS Help under …

14.06.2021 · Fig. 01 Screenshot of FEM solver options available in SimScale. As shown in Fig. 01, we can see that, for structural mechanics simulations, there are several options available in the numerics section of the SimScale cloud-based platform. Of these, Multfront, MUMPS, and LDLT are direct solvers, while PETSc and GCPC are iterative solvers.

If using the latest version of HFSS try using iterative solver rather than direct solver, this will reduce the memory usage.

There are three solver methods in HFSS: Direct, Iterative and Domain solvers. Iterative solver uses a "guess and check" type of algorithm ...

15.07.2020 · 1. HFSS solver failed to start while performing a frequency sweep. A common problem in running HFSS using ANSYS AEDT is the failure to run a frequency sweep even though the main solution solves. The problem resides in the HPC settings and the license you may have purchased. The discrete frequency sweep fails if you do not have the license ...

07.05.2021 · The next significant solver advancement was the introduction of the first iterative solver in 2007. The iterative solver is great for complex designs with RAM limitations. In 2009, the domain decomposition method, DDM [4] enabled the HFSS solver to be used across multiple compute nodes to access both more cores for speed and more memory for ...

19.04.2019 · This paper presents an overview of the iterative solver in ANSYS HFSS for solving large-scale problems obtained from the finite element analysis of time-harmonic Maxwell's Equations. To this end, Krylov subspace methods with effective preconditioning and parallelizable routines are presented to extend the applicability and efficiency of frequency domain solver. …

How should you choose a FEM solver for a simulation? What is the difference between direct and iterative solvers? Find out now!

HFSS15: Iterative Matrix Solver Technical Details. The iterative solver always saves significant memory - easily a factor two with simulations of intermediate size, and more with larger simulations. It is also faster than the multi-frontal solver with large simulations. The following table shows asymptotic behavior with large simulations.

Hi, I am going to simulate structure at THz frequencies and i want to know what solver to use Direct or Iterative.
