Member Data Documentation
◆ df
| real(dp) frictiontypemodule::frictiontype::df |
Change in force between last two iterations.
◆ edmp
| real(dp) frictiontypemodule::frictiontype::edmp |
Energy loss (always positive)
◆ eng
| type(enginetype), pointer frictiontypemodule::frictiontype::eng |
User-defined normal load.
◆ fequ
| real(dp) frictiontypemodule::frictiontype::fequ |
Equivalent normal force.
◆ fext
| real(dp) frictiontypemodule::frictiontype::fext |
Force that should match friction force on stick.
◆ fmax
| real(dp) frictiontypemodule::frictiontype::fmax |
Max friction force.
◆ force
| real(dp) frictiontypemodule::frictiontype::force |
Current force.
◆ forceprev
| real(dp) frictiontypemodule::frictiontype::forceprev |
Force at the end of last time step.
◆ forceprevit
| real(dp) frictiontypemodule::frictiontype::forceprevit |

The value has the following interpretation:
- = 0: No initialization (within iteration loop)
- = 1: Initialize for a new time step
- = 2: Initialize for start of simulation

◆ pos0
| real(dp) frictiontypemodule::frictiontype::pos0 |
Position at start of time step.
◆ posprev
| real(dp) frictiontypemodule::frictiontype::posprev |
Position at the end of last time step.
◆ posprevit
| real(dp) frictiontypemodule::frictiontype::posprevit |
Position at previous iteration.
◆ savevar
| logical, dimension(3) frictiontypemodule::frictiontype::savevar |
Flags indicating which variables should be saved.
◆ spr
| type(springbasetype), pointer frictiontypemodule::frictiontype::spr |
Spring with variable yield to handle stick stiffness.
◆ stiff
| real(dp) frictiontypemodule::frictiontype::stiff |
Relative change in friction force wrt. velocity.
◆ vel
| real(dp) frictiontypemodule::frictiontype::vel |
