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
