dear all, i want to use the duns code to solve my N--S equations.when i run it in OS of Linux7.2, some warning happened. the major problem is the code: #if ...#endif . anybody run it successfully in linux os? or Unix? thanks a lot .

Did you look at the bugs on the sourceforge website for the DUNS? Bug #508861 is most likely your problem.

I suspect that you have a problem with pre-processing. I found it necesssary to add the -traditional option for the cpp pre-processor in the MakeSystem file.

this is the error i encounted. could you tell me how to revise the makesystem file? i do not learn linux well. Which line '-traditional -cpp' will be added to? thanks again and best regards Martin J

could you tell me how to revised the file MakeSystem, that is which line -traditional is added to? best regards

ps:this is the makesystem file that i revised.is it right? the error exit too!

Martin,

You can try changing the Makesystem file to look like this. Basically only 2 changes:

1. g77 actually works fine 2. add -traditional to the list of options for CPP

# # This makesystem was constructed on a PII machine running Linux. # We found we had to use fort77 (front-end to f2c) # instead of g77/f77 that comes with most distributions, although # we still link with the g2c directory. Enjoy. #

.SUFFIXES: .Inc .inc .o .F .C .f .cpp .c

#F77 = fort77 F77 = g77 CPP = gcc -C -x c -P -E -traditional CPLUS = g++ CC = gcc LINKER = gcc LIBMAKER= ar vr MKDIR = /bin/mkdir -p RM = /bin/rm -f CP = /bin/cp -f CHMOD = /bin/chmod

Trying to building on an old sun system problems seemed to lie with the (unnecessary) build scripts rather than cpp. Copying the src directory to a new directory, adding the "makesystem" parameters to the Makefile, adding the required cpp flags (-DTWOD -DFUNDER for a quick test) and the solver and plotting programs built OK. I also had to add a CHMOD parameter to the "makesystem" file and one or two other things to do with the graphics in order to build the library the plotting program seemed to want.

>>> fort77 -O2 -w -c prepar.f prepar.f

This command is wrong: it is using the same name for the source and object files.

The duns program is a fairly standard university CFD research code and is not a "FLUENT" substitute. To use it effectively I strongly suspect you are going to need to know how to program and how to use standard programming tools like cpp, cc, f77, ld, make,...

I also suspect there might be copyright issues if you try to work with the code. The copyright of almost all university developed code lies with the university and not the researchers and there is no mention in the HISTORY or COPYRIGHT files that MIT/Penn State/... have surrendered their rights. Perhaps they have but it would be an unusual omission given the efforts one would normally have to make to get this agreement.

That looks like a pre-processing error; you should not have any #ifdef ... #else ... #endif lines in your FORTRAN (.f) files.

If you are running on Redhat 8 or 9 (this will probably work with 7 also), the CPP line should read:

CPP = gcc -C -x c -P -E -traditional-cpp

in makesystem/Makesystem_linux

and it should preprocess the files correctly. The newer versions of gcc will mess with the white-space unless the '-traditional-cpp' flag is used, which then messes up the FORTRAN compiler.

Try doing on of the test cases, such as serial/bfs, to see if things are set up correctly.

Good luck! Doug

hi, i can not solve the problem, because the errors come again.

SUFFIXES: .Inc .inc .o .F .C .f .cpp .c

F77 = fort77 CPP = gcc -C -x c -P -E -traditional -cpp

is it right??

thanks for you help, best regards Martin
