Governing Equation (2D):
Shallow water droplet equation.
Ut + A(U)x + B(U)y = 0

where,
U = [rho rho*u rho*v], A = [rho*u, rho*u^2+rho^2, rho*u*v], B = [rho*v, rho*u*v, rho*v^2+rho^2]


I am trying diccretize the convective fluxes by Roe upwind scheme.


I implimented following steps:


  • Making of two new directories in dbns. They are basicNumericFlux1 and NumericFlux1 and made all the necessary changes.


  • Making a new directory in dbnsFlux which is roeDropletFlux by changing roeFlux.


  • Compilation was made from src directory by Allmake.


p { margin-bottom: 0.1in; line-height: 115%; }

I think compilation was successful. I am attaching the message after compilation:

dbnsFlux/roeDropletFlux/roeDropletFlux.C:86:18: warning: unused variable ‘qTildeSquare’ [-Wunused-variable]
const scalar qTildeSquare = magSqr(UTilde);

No nvcc - CUDA not available.

Next I created a directory in applications under compressible as dbnsDropletTurbFoam from dbnsTurbFoam.


I implimented following steps:


  • Creation of dbnsDropletTurbFoam.C.
  • Updating createFields.H.
  • Modifying updateFields1.H and readFieldBounds1.H and placing in same directory.


I made the necessary changes in the Make file.
In files:


dbnsDropletTurbFoam.C
EXE = $(FOAM_USER_APPBIN)/dbnsDropletTurbFoam


and in options:


EXE_INC = \
-I$(LIB_SRC)/finiteVolume/lnInclude \
-I$(LIB_SRC)/thermophysicalModels/basic/lnInclude \
-I$(LIB_SRC)/thermophysicalModels/specie/lnInclude \
-I$(LIB_SRC)/turbulenceModels/compressible/turbulenceModel \
-I$(LIB_SRC)/dbns/lnInclude


EXE_LIBS = \
-lfiniteVolume \
-lbasicThermophysicalModels \
-lspecie \
-lcompressibleTurbulenceModel \
-lcompressibleRASModels \
-lcompressibleLESModels \
-ldbns \
-llduSolvers


Although many of the libraries are not required, but still I retained it unchanged.

Now I am receiving following errors after compilation with wmake:


/home/bidesh/foam/bidesh-4.0/applications/bin/linux64GccDPOpt/dbnsDropletTurbFoam
/home/bidesh/foam/foam-extend-4.0/lib/linux64GccDPOpt/libdbns.so: undefined reference to `Foam::basicNumericFlux1::destroystateConstructorT ables()'
/home/bidesh/foam/foam-extend-4.0/lib/linux64GccDPOpt/libdbns.so: undefined reference to `Foam::basicNumericFlux1::constructstateConstructo rTables()'
/home/bidesh/foam/foam-extend-4.0/lib/linux64GccDPOpt/libdbns.so: undefined reference to `Foam::basicNumericFlux1::stateConstructorTablePtr _'
collect2: error: ld returned 1 exit status
/home/bidesh/foam/foam-extend-4.0/wmake/Makefile:159: recipe for target '/home/bidesh/foam/bidesh-4.0/applications/bin/linux64GccDPOpt/dbnsDropletTurbFoam' failed
make: *** [/home/bidesh/foam/bidesh-4.0/applications/bin/linux64GccDPOpt/dbnsDropletTurbFoam] Error 1

Then I went through online resources and applied wmake libso, which seemed to have compiled successfully with the following message:



/home/bidesh/foam/foam-extend-4.0/src/foam/lnInclude -I/home/bidesh/foam/foam-extend-4.0/src/OSspecific/POSIX/lnInclude -fPIC -c $SOURCE -o Make/linux64GccDPOpt/dbnsDropletTurbFoam.o

'libNULL.so' is up to date.

But the compilation was not sucessful as it is not recognising dbnsDropletTurbFoam.

dbnsDropletTurbFoam: command not found



I am unable to understand the mistake, can you kindly suggest me to overcome this problem. I apologies for such big post, but I wanted to explain the problem that I am encountering.



Thank you,
Bidesh.
