Frictions
Frictions entities define friction coefficients between parts.

| FRICT / | Friction modeling definition. Several friction models are available for use in the sliding interface contacts. A given model type is specified through the IFROPT, standard Coulomb friction (IFROPT= 1) and Velocity-Dependent Friction by Curve model (IFROPT= 3) can be used in the Slipring definition. |
| FRICT / IFROPT = 1 | Standard Coulomb Friction Model. |
| FRICT / IFROPT = 2 | Pressure-Dependent Friction by Curve. |
| FRICT / IFROPT = 3 | Velocity-Dependent Friction by Curve |
| FRICT / IFROPT = 4 | Pressure- and Velocity-Dependent Friction by Curves. |
| FRICT / IFROPT = 5 | Pressure-Dependent Friction by Standard Function 1. |
| FRICT / IFROPT = 6 | Pressure-Dependent Friction by Standard Function 2. |
| FRICT / IFROPT = 10 | Orthotropic Friction. |
| FRICT / IFROPT = 11 | Orthotropic Friction with Arbitrary Orientation. |
| FRICT / IFROPT = 12 | User-Defined Friction Model. |
| FRICT / IFROPT = 13 | Lookup Table Dependent on Pressure, Velocity and Temperature. |
| FRITAB/ | Friction Table Definition. Directly define the friction per part pair using a friction table. |

You can define the friction coefficient CF while creating a .MCT through the エンティティエディター or the panel. Also, a provision is given to define a curve that can be linked to the CF. The parameter where the curve is assigned or linked to the CF is called CFNF.
