PBiCG VS smoothsolver

Posted March 31, 2017 at 12:51 by kindle
Updated May 11, 2017 at 10:21 by kindle (OF-4.x and Foam-extend have implemented this solver)
Namings of libraries are different in OpenFOAM and foam-extend. Well. BiCGStab is needed in U solver of viscoelasticFluidFoam

And this PBiCGStab is implemented also in the OF-4.x and foam-extend (go downstairs from the post). More specifically in OF-4.x it is added (https://github.com/OpenFOAM/OpenFOAM-4.x/commit/1ca4bbf1d288075a76940d58fdf61cbfc49298ee) and in foam-extend it is modified (https://github.com/OpenFOAM/OpenFOAM-dev/commit/c339d3018c98cb67c3455ab09db316c7c0618d5c).

could not open file ** for ** when compiling

Posted March 31, 2017 at 12:46 by kindle
if the problem is :
could not open file ** for xx due to No such file or directory. Maybe it's that after option -I you have a blank space before the INC directory.

Code:
-I$(LIB_USER_SRC)/viscoelasticFluidFoam-1.0-OpenFOAM-2.1.x/src/transportModels/viscoelastic/lnInclude
will do but
Code:
-I $(LIB_USER_SRC)/viscoelasticFluidFoam-1.0-OpenFOAM-2.1.x/src/transportModels/viscoelastic/lnInclude
may not.

  1. Made a copy of the tutorial "lagrangian/DPMFoam/Goldschmidt" and ran the utility blockMesh.
  2. Then I had to look at which file needed to modified. All pointed to the file "constant/kinematicCloudProperties".
  3. Now I had

debug version will give line numbers. Ok. May worth the cost.

My guess is that this is (again) the old "I set k/epsilon/omega to 0 in the initial conditions (or
