All LORENTZ packages provide the choice of Boundary Element Method (BEM) or Finite Element Method (FEM) field solvers. BEM is often the preferred method for electric problems and precise calculations of fields in open regions. FEM often provides faster solutions for heavily saturated magnetic problems.
An additional advantage to having both solution methods is the ability to confirm the validity of models using two independent solvers based on entirely different mathematical formulations.
A Finite Difference Time Domain (FDTD) solver is available for applications requiring the analysis of high frequency electromagnetic fields.
All LORENTZ packages provide the choice of four different Ordinary Differential Equation (ODE) solvers for trajectory computations:
- Constant Step Runge-Kutta 4 (RK4)
- Adaptive Runge-Kutta 5 (RK5)
- Adaptive Runge-Kutta 853 (RK853)
- Adaptive Bulirsch-Stoer
