ContactMechanics.CommandLineInterface.HardWall module

Command line front-end for hard wall calculations

ContactMechanics.CommandLineInterface.HardWall.dump(txt, surface, substrate, u, f, offset=0)
ContactMechanics.CommandLineInterface.HardWall.dump_nc(container, u, f, disp0, load, area)
ContactMechanics.CommandLineInterface.HardWall.main()
ContactMechanics.CommandLineInterface.HardWall.next_step(system, surface, history=None, pentol=None, maxiter=None, logger=<ContactMechanics.Tools.Logger.Logger object>, verbose=False)

Run a full contact calculation. Try to guess displacement such that areas are equally spaced on a log scale.

Parameters:

  • system (PyCo.System.SystemBase object) – The contact mechanical system.

  • surface (SurfaceTopography.SurfaceTopography object) – The rigid rough surface.

  • history (tuple) – History returned by past calls to next_step

  • pentol (float, optional) – Penetration tolerance, passed to CG solver. (Default: None)

  • maxiter (int, optional) – Maximum number of iterations, passed to CG solver. (Default: None)

  • verbose (bool, optional) – Output verbosity. (Default: False)

Returns:

  • displacements (numpy.ndarray) – Current surface displacement field.

  • forces (numpy.ndarray) – Current surface pressure field.

  • displacement (float) – Current displacement of the rigid surface

  • load (float) – Current load.

  • area (float) – Current fractional contact area.

  • history (tuple) – History of contact calculations.
