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:
“

const scalar qTildeSquare = magSqr(UTilde);

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

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.
