The TAILSIT EM solver
Core technology
POLARIS and our customer projects are built on the same computational kernels: scalable FEM, BEM and coupled solvers for electromagnetic fields.
The solver
Physics
Electrostatic, magnetostatic and eddy current problems, in frequency and time domain.
FEM, BEM and coupled FEM–BEM
Scalable solvers with MPI and threading.
Fast Multipole Method
Compressed boundary element matrices and advanced preconditioners.
No air mesh
The surrounding air doesn't have to be modelled.
Multiphysics coupling
Forces and losses passed to structural and thermal solvers. See the case studies.
COMPUMAG TEAM benchmarks
The TEAM workshop problems of the International Compumag Society let solvers be compared on shared test cases, many of them with published measurements. Click an image to enlarge it.
Problem 13
Average magnetic flux density along the steel plates, simulation against measurements.
Problem 28
Levitation device: height over time, compared with measurements and a published BEM-FEM result.
Problem 33
Electrostatics: electric forces on a conductor (Problem 33b).
