Detailed Description

Derived class for Plastic till ice Stream with Thermocoupling (PST) experiments.

Runs numerical experiments reported in BBssasliding .

There are four experiments, P1,P2,P3,P4. Each has four (three for P2) ice streams generated by lowered till friction angle.

(This derived class supercedes an older class which produced results presented by Bueler at AGU 2007 and at NYU in Feb 2008. IcePSTexModel has no "lake" or "fjord", which were present in the old version.)

Member Function Documentation

PetscErrorCode additionalAtEndTimestep ( ) [virtual]

Virtual. Does nothing in IceModel. Derived classes can do more computation in each time step.

Reimplemented from IceModel.

PetscErrorCode allocate_basal_yield_stress ( ) [virtual]

Decide which basal yield stress model to use.

Reimplemented from IceModel.

Definition at line 319 of file icePSTexModel.cc.

References IceModel::basal_yield_stress, IceModel::config, exper_chosen, exper_chosen_name, and IceModel::grid.

PetscErrorCode allocate_stressbalance ( ) [virtual]

Decide which stress balance model to use.

Reimplemented from IceEISModel.

Definition at line 329 of file icePSTexModel.cc.

References PISMStressBalance::get_stressbalance(), secpera, SSAStrengthExtension::set_notional_strength(), SSA::strength_extension, and IceModel::stress_balance.

PetscErrorCode initFromFile ( const char * filename ) [virtual]

Read a saved PISM model state in NetCDF format, for complete initialization of an evolution or diagnostic run.

Before this is run, the method IceModel::grid_setup() determines the number of grid points (Mx,My,Mz,Mbz) and the dimensions (Lx,Ly,Lz) of the computational box from the same input file.

Reimplemented from IceModel.

PetscErrorCode set_vars_from_options ( ) [virtual]

Only executed if NOT initialized from file (-i).

Reimplemented from IceEISModel.

PetscErrorCode setFromOptions ( ) [virtual]

Read runtime (command line) options and alter the corresponding parameters or flags as appropriate.

A critical principle of this procedure is that it will not alter IceModel parameters and flags unless the user sets an option to do so. This base class setFromOptions() can be called by an IceModel-derived class after the it has set its own defaults.

In fact this procedure only reads the majority of the options. Some are read in initFromOptions(), writeFiles(), and setStartRunEndYearsFromOptions(), among other places.

There are no options to directly set dx, dy, dz, Lbz, and year as the user should not directly set these grid parameters. There are, however, options for directly setting Mx, My, Mz, Mbz and also Lx, Ly, Lz.
