Initial commit for multilevel amrmpm
This is just a copy of amrmpm

734 lines of code changed in 1 file:

• CCA/Components/MPM/Matlab: ML_AMRMPM.m (new 734)

harman 2009-12-21 16:20 Rev.: 45221

pulled initialization functions out of AMRMPM.m and put them in
initializationFunctions.m

269 lines of code changed in 4 files:

• CCA/Components/MPM/Matlab: AMRMPM.m (changed), initializationFunctions.m (new 269), initializeRegions.m (del)

Changes so you can read in a file that contains the L2norm and maxError
to compute the order of accuracy

2nd order accuracy for MMS problem
A = 0.05
t_initial = 0.0
t_final = wavelength
constant resolution

• CCA/Components/MPM/Matlab: AMRMPM.m (+2 -2), MMS.m (new), initializeRegions.m (new 87)

harman 2009-12-18 11:28 Rev.: 45213

order of accuracy result for the MMS problem, PPC:2, A = 0.001
NN = [22, 46, 64, 130, 262, 514]

Now using initializeRegions()

Took out most of the hard coded code. You should be able to switch between
plots of the linear & gimp functions by changing "interpolation"

added asci-art, hopefully it's a little clearer what is going on.

• CCA/Components/MPM/Matlab: plotShapeFunctions.m (new)

harman 2009-12-17 19:02 Rev.: 45211

More informative error messages.

PositionToClosestNodes()
- Can now handle computational domains that have regions that are negative.

harman 2009-12-17 19:00 Rev.: 45210

define a new region used specifically for plotShapeFunction.m

NN is now computed in initializeRegions.m

Define extra cells on the outermost regions (not used)

31 lines of code changed in 2 files:

• CCA/Components/MPM/Matlab: AMRMPM.m (-1), initializeRegions.m (+31 -1)

harman 2009-12-16 17:56 Rev.: 45204

pulled out all of the shape functions and placed them in a separate .m file.

Something is not working correctly with plotShapeFunctions.

495 lines of code changed in 3 files:

• CCA/Components/MPM/Matlab: AMRMPM.m (+9 -444), plotShapeFunctions.m (+30 -244), shapeFunctions.m (+456)

harman 2009-12-16 16:05 Rev.: 45203

The initial time is now a variable, t_initial.

Removed sections of debugging plots.

• CCA/Components/MPM/Matlab: AMRMPM.m (+20 -41)

harman 2009-12-16 15:54 Rev.: 45202

added debugging functions
MMS_acceleration()
MMS_dFdx()
MMS_divergenceStress()

44 lines of code changed in 1 file:

• CCA/Components/MPM/Matlab: MMS.m (+44 -5)

harman 2009-12-10 17:07 Rev.: 45192

Restructuring:
- extForceP -> accl_extForceP
- moved all MMS related functions to MMS.m, and using function handles.

- use structures to minimize the function call lengths.

211 lines of code changed in 2 files:

• CCA/Components/MPM/Matlab: AMRMPM.m (+67 -151), MMS.m (+144)

harman 2009-12-09 17:57 Rev.: 45190

MMS_displacment()
MMS_deformationGradient()
MMS_velocity()
MMS_bodyForce
-Now dividing all trigometric functions by h or bar_length.
- dividing h in leading equation terms.

Pull out multiplcation of the bodyForce by massP to be consistent with
interpolate particles to grid section.

This shouldn't change the answers

harman 2009-12-03 12:23 Rev.: 45154

Added plotInterval variable.

MMS: L2norm & maxError are computed on every timestep

Added vertical lines at the node locations in two of the plots.

Current answers:
[L2_norm, maxError, NN, NP]=amrmpm('mms',0.1,22)
L2_norm = 7.5877320255472670E-04
maxError = 1.0740790335386496E-03
