mhomel 2014-11-28 20:27 Rev.: 52764

Added p.velocity as a <geom_object><file><var> option for pts files with spatially varying initial velocity

1 lines of code changed in 1 file:

• StandAlone/tools/pfs: pfs2.cc (+1)

Modified the step division, and improved the algorithm for computing the interior point in nonHardeningReturn

mhomel 2014-09-26 18:26 Rev.: 52506

Added code that will hopefully prevent the code from hanging in the nonHardening return loop.

Turned fastapproximatefunctions off by default. Can be enabled by #define MHfastfcns in Arenisca3.cc

Fixed the poisson scaling bug, previously fixed in Arenisca 3

mhomel 2014-09-17 16:33 Rev.: 52455

Fixed a bug in the step divide code, causing it to erroneously use an overly conservative dtep division.
New version is much faster and seems stable but let me know if you have any robustness issues.

mhomel 2014-09-14 21:39 Rev.: 52443

Added Lode angle dependence with Mohr Coulomb and Gudehus options. Added inputs for Lode angle functions and max princ stress.
Replaced some functions with lookup tables but still slow.

• CCA/Components/MPM/ConstitutiveModel: Arenisca4.cc (+124 -167), Arenisca4.h (+4 -4)

mhomel 2014-09-14 20:13 Rev.: 52442

changed input types for Arenisca4 3rd invariant dependence paramters

• CCA/Components/MPM/ConstitutiveModel: Arenisca4.cc (+110 -25)

mhomel 2014-09-14 19:34 Rev.: 52440

Arenisca 4 no working with structure to support 3rd invariant dependence. Passes the A3 benchmarks.
Still needs inputs for Lode angle function and faster implementation.

mhomel 2014-09-10 03:37 Rev.: 52410

Eliminated the requirement for monotonically increasing insertParticle() times

mhomel 2014-09-10 03:33 Rev.: 52409

Fixed a typo in the poisson scaling for arenisca3. Rewrote Arenisca4 to allow for 3rd invariant dependence. It builds but has not been tested yet at all.

mhomel 2014-08-28 19:02 Rev.: 52364

Added input error checking, scaling of elastic properties with disaggregation (timestep control).
Also moved computation of sqrt(3k/2g) and limit paramters out of deep loops for significant
efficiency gain.
