# Hysteretic Model Properties

The properties of the Hysteretic Model model are shown below for reference. More detailed information regarding these properties is presented here.

Note

Some properties are read only as stated below.

- hysteretic
- dp_en f
\(e_n\) - target restitution coefficient with default value 1.0.

- dp_enmin f
\(e^*_n\) - minimal restitution coefficient with default value 0.0.

- dp_force v
\(\mathbf{F^{d}}\) - dashpot force. Expressed in the contact plane coordinate system. This is a read-only property.

- dp_mode i
\(M_d\) - dashpot mode with default value 0.

- fric f
\(\mu\) - friction coefficient with default value 0.0.

- hz_alpha f
\(\alpha\) - exponent with default value 1.5.

- hz_force v
\(\mathbf{F^{h}}\) - hertz force with default value \(\mathbf{0}\). Expressed in the contact plane coordinate system.

- hz_mode i
\(M_s\) - shear-force scaling mode with default value 0.

- hz_poiss f
\(\nu\) - poisson’s ratio with default value 0.0.

- hz_shear f
\(G\) - shear modulus in units stress with default value 0.0.

- hz_slip b
\(s\) - slip state. This is a read-only property.
