Detailed Description

BasalFriction that computes $\beta^2$ from data on a uniform grid.

Run time configuration is carried out in BasalFriction::parse(A, ... ) If the option A.beta_type = LevelData is found, then the expected form is:

inputLevelData.frictionFile = <string>
inputLevelData.frictionName = <string>

for a single file or

inputLevelData.frictionFileFormat = <string>
inputLevelData.frictionName = <string>
inputLevelData.frictionFileStartTime = <int>
inputLevelData.frictionFileTimeStep = <int>

for a sequence of files

factory method

Returns: a pointer to a new BasalFriction object

Implements BasalFriction.

◆ setBasalFriction()

void LevelDataBasalFriction::setBasalFriction	(	LevelData< FArrayBox > &	a_betaSqr,
		LevelSigmaCS &	a_coordSys,
		Real	a_time,
		Real	a_dt
	)

virtual

compute basal friction coefficient beta^2 and place in a_betaSqr

time and dt are included in case this is time-dependent. Units should usually be chosen so that the basal traction $\tau_b(\beta^2, u)$ is measured in Pascals when $u $ is measured in meters per year.
