Several lumped elements can be applied in pure electric circuit, circuit coupled magnetic, piezoelectric, and coupled electromechanical analyses. For more information about degrees of freedom, through variables (force, reaction force), and element compatibility, refer to this guide, the Element Reference, and Element Compatibility.

CIRCU94 is a circuit element with electric potential (VOLT) degree of freedom and positive or negative electric charge through variable (force, reaction force). Depending on KEYOPT selection it can act like a linear resistor, capacitor, inductor, or an independent voltage or current source. CIRCU94 can be applied in connection with other elements having the same degree of freedom and through variable (force, reaction force). Electric charge reaction signs must all be positive or negative. For example, CIRCU94 can be combined with the following elements to simulate circuit coupled piezoelectric analysis: SOLID5, PLANE13, SOLID98, PLANE222, PLANE223, SOLID225, SOLID226, and SOLID227. It can also work together with PLANE121, SOLID122, and SOLID123 to simulate circuit fed electrostatic analysis.

CIRCU124 is a circuit element with electric potential (VOLT) degree of freedom and electric current (AMPS label) through variable (force, reaction force). Depending on KEYOPT selection it can act like a linear resistor, capacitor, inductor, or a number of circuit source or coupled circuit source options. CIRCU124 can be applied in connection with other elements having the same degree of freedom and through variable (force, reaction force): SOLID5, LINK68, SOLID98, CIRCU125, TRANS126, PLANE222, PLANE223, SOLID225, SOLID226, SOLID227, PLANE230, SOLID231, and SOLID232. CIRCU124 can also work together with PLANE13 magnetic elements to simulate circuit fed magnetic analysis.

CIRCU125 is a circuit element with electric potential (VOLT) degree of freedom and electric current (AMPS label) through variable (force, reaction force). Depending on KEYOPT selection it can act like a regular or Zener diode circuit. CIRCU125 can be applied in connection with other elements having the same degree of freedom and through variable (force, reaction force): CIRCU124, TRANS126, and LINK68.

TRANS126 is an electromechanical transducer with electric potential (VOLT) as well as mechanical displacement (UX, UY, UZ) degrees of freedom and electric current (AMPS label), as well as mechanical force (FX, FY, FZ) through variables (force, reaction force). TRANS126 can be applied in connection with other elements having the same degree of freedom and through variable (force, reaction force): CIRCU124, CIRCU125, and LINK68. It can also be applied in connection with all regular mechanical elements to simulate strongly coupled electromechanical interactions, a characteristic of MEMS design.
