The code below manages the update of a certain boundary condition (BCId) to assume values progressing from begin to end values within nsteps, such that the last step length is a 'lastStepRatio' fraction of the global load in a geometric progression.

Parameters

out	[in] output device to write the output to
tol	[in] tolerance desired in each loading step
numiter	[in] maximum iteration steps in each loading step
BCId	[in] boundary condition Id
nsteps	[in] number of steps
PGRatio	[in] ratio for the PG progression
val1Begin	[in] beginning value of BC.Val1
val1End	[in] final value of BC.Val1
val2Begin	[in] beginning value of BC.Val2
val2End	[in] final value of BC.Val2
ppAnalysis	[in] TPZPostProcAnalysis object to write the output to
res	[in] output postprocessing resolution
