Commit by bueler :: r1206 /trunk/ (8 files in 4 dirs):

Fixed diagnostic diffusivity (of SIA) calculation: now it happens only in one place, namely velocitySIAStaggered(). We save diffusivity on staggered grid, in memory also used for 'hardav' in SSA; this is now IceModelVec2Stag vWork2dStag. Also a bit more reporting on bed smoother initialization.

Added and documented option -bed_smoother_range. Added slightly to performance...

Commit by bueler :: r1204 /trunk/ (8 files in 5 dirs):

Generally bed smoother/roughness-parameterizer ready to go. Thickness details (margin) fiddles done. Derived classes turn the mechanism off. Half-width of smoothing domain set to 5km, but not that there is always one grid point in each direction if the mechanism is on at all. Remains to add option adjusting this range.

Improved bed roughness parameterization scheme by recognizing 4th order Taylor polynomial was convex like the function it is approximating. Updated tools to reflect that.

Commit by bueler :: r1201 /trunk/src/ (4 files in 2 dirs):

Clean up of r1200 commit: revert changes to iceModelVec2.cc (why can't global go to proc0?); fix bedrough_test.cc so test 26 passes; clobber 'possibly uninitialized poly_ice' compile warning for flowlaw_test.cc. Test 22 still fails, but this failure un-observable by eye.

Commit by bueler :: r1199 /trunk/ (10 files in 6 dirs):

Working PISMBedSmoother, still not attached to IceModel (that is next). Added min() and max() capability to IceModelVec2S, but have not used it in many possible applications in IceModel.

Commit by ckhroulev :: r1197 /trunk/ (4 files in 3 dirs):

Added flowlaw_test, an executable similar to flowTable. flowlaw_test accepts the -ice_type command-line option but does not compute GK parts. It is used by the flow law regression tests 24 and 25.

Commit by bueler :: r1189 /trunk/ (5 files in 2 dirs):

Testing on marmaduke reveal that r1187 produces small differences on different machines for tests 22 and 23; may be libraries? In any case, tolerances lowered to generally 10^-7 with several exceptions down to 10^-5.
