openCFS-Data: Data Pre-Post-Processing Tool for openCFS
Stefan Schoder, Klaus Roppert
Many numerical simulation tools have been developed and are on the market, but there is still a strong need for appropriate tools capable to simulate multi-field problems, especial…
openCFS: Open Source Finite Element Software for Coupled Field Simulation -- Part Acoustics
Stefan Schoder, Klaus Roppert
The finite element method offers attractive methods for the numerical solution of coupled field problems arising in sensors and actuator simulations of various physical domains, li…
On energy consistent vector hysteresis operators
Herbert Egger, Felix Engertsberger, Lukas Domenig +2
Incremental models for magnetic vector hysteresis have been developed in previous works in accordance with basic principles of thermodynamics. In this paper, we present an equivale…
On nonlinear magnetic field solvers using local Quasi-Newton updates
Herbert Egger, Felix Engertsberger, Lukas Domenig +2
Fixed-point or Newton-methods are typically employed for the numerical solution of nonlinear systems arising from discretization of nonlinear magnetic field problems. We here discu…
