FEM ConstraintElectrostaticPotential/de

Beschreibung
Erstellt eine FEM-Randbedingung für das elektrostatische Potential, zur Verwendung mit der ElektrostatischenGleichung oder der ElectricforceGleichung.

Anwendung

 * 1) Die Schaltfläche  drücken oder den Menüeintrag  auswählen.
 * 2) In der 3D-Ansicht das Objekt auswählen, dem die Randbedingung zugeordnet werden soll.
 * 3) Die Schaltfläche  Drücken.

Optionen
Der Dialog Eigenschaften der Analyseelemente ermöglicht die folgenden Einstellungen:




 * Potential: The electric potential in V.
 * unspecified': To declare the potential as unknown for the solver.
 * Vector Field: To enable the input of the components of a potential vector field.
 * x: The real/imaginary part of the potential in x-direction in V. For other coordinate systems than Cartesian 3D, this will be the first coordinate of the system instead of x.
 * y: The real/imaginary part of the potential in y-direction in V. For other coordinate systems than Cartesian 3D, this will be the second coordinate of the system instead of y.
 * z: The real/imaginary part of the potential in z-direction in V. For other coordinate systems than Cartesian 3D, this will be the third coordinate of the system instead of z. If the coordinate system has no third coordinate, this setting will be ignored.
 * x, y, z checkboxes: To declare the corresponding potential as unknown for the solver.
 * Potential Constant: Option to set a constant potential.
 * Farfield / Electric infinity: Option to make spherical approximation that the volume above the face extends to infinity.
 * Calculate Electric Force: Option to trigger the calculation of the electric force using the Electricforce equation.
 * Capacity Body: : Counter of the body (or face) with a capacitance.
