Current state :

Solver :

  • Electrostatic planar and axissymmetric problems
  • Stationary current planar and axissymmetric problems
  • Magnetostatic planar and axissymmetric problems
  • 1D and 2D triangular Elements for all problem types
  • Dirichlet and Neumann boundary conditions for all problem types and Elements

Postprocessing :

  • Display of calculated values depending on selected problem
    • Electrostatic : V, E, D
    • Stationary current : V, E, J
    • Magnetostatic : A, B, H
    • For vector values :
      • Abs, Abs mesh, Quiver, Slice, Field lines - plots
    • For scalar values :
      • Abs, Abs mesh, Slice - plots
    • Additional options
  • Calculate field or potential along a curve defined by a list of points and the total number of points to interpolate
  • Calculate field or potential for selected mesh (zoom in and out)
  • Calculate energy for selected region :
    • Electrostatic
    • Magnetostatic
