The properties of the Adhesive Rolling Resistance Linear Model are shown below for reference. More detailed information regarding these properties is presented here.

Note

Some properties are read only as stated below.

arrlinear

adh_d0 f

\(D_0\) - attraction range with default value 0.0.

adh_f0 f

\(F_0\) - maximum attractive force with default value 0.0.

adh_force f

\(F^a\) - attractive force with default value 0.0. This is a read only property.

dp_force v

\(\mathbf{F^d}\) - dashpot force in units 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.

dp_nratio f

\(\beta_n\) - normal critical damping ratio with default value 0.0.

dp_sratio f

\(\beta_s\) - shear critical damping ratio with default value 0.0.
