This equation perform electrostatic analyses using Gauss' law.

For info about the math of the equation, see the Elmer models manual, section Electrostatics.

Usage

  1. After adding an Elmer solver as described here, select it in the tree view.
  2. Now either use the toolbar button or the menu Solve → Electrostatic equation.
  3. Change the equation's solver settings or the general solver settings if necessary.

Solver Settings

For the general solver settings, see the Elmer solver settings.

The electrostatic equation provides these special settings:

Constraint Information

The electrostatic equation takes the following constraints into account if they are set:

Note

Except for calculations in 2D, for electrostatic potential constraints it is important that they act on a face or body. Constraints for 3D set to lines or vertices are not recognized by the Elmer solver.
