hi,i am a beginner of openFoam

hi,i am a beginner of openFoam.i downloaded a FSI case and its solver, but i don't know how to creat a class on my own,how to use the solver.could anyone help me?

thanks for help in advance

Hi Wang Wish you a good day

Hi Wang

Wish you a good day.

Please be more specific and post the screen output and errors from your attempts as for now it is not clear what actually the problem is.

please tell me what you tried and where things went wrong.

Also please consult user guide if you haven't done that yet.

Kind Regards
Jaswinder

hi Jaswinder, thanks for your

hi Jaswinder, thanks for your response.
i am trying to use a solver of FSI.but i do not know how to do it,so i first follow steps i found on a website to create a solver by modify a pre-defined solver,here is the address:
http://www.csc.fi/english/research/s...enfoam/modsol/

at the beginning,everything is fine,
but when i inuput "emacs Make/files"
and the terminal tells me:
The program 'emacs' can be found in the following packages:
* emacs21-nox
* emacs22-gtk
* emacs22
* emacs-snapshot
* e3
* emacs-snapshot-nox
* emacs21
* emacs22-nox
* jove
* emacs-snapshot-gtk
Try: sudo apt-get install <selected>
bash: emacs: command not found

i do not what is the problem,so i creat a file manully which the coresponding step on the website want me to creat
after that i input "wmake",problems also comes up
,the terminal tells me:

these are just part of the errors ,for it is too long.sorry about that

So could you give me some advice on how to deal with it?

kindly regards

hi ,i try it ,but it seems i can not creat an executable in the
/home/fw407/OpenFOAM/fw407-1.4.1/applications/bin/linuxGccDPOpt directory

could anyone help me?

hi, most of the upper error

hi,

most of the upper error lines look like your compiler believes that used commands like scanf,printf do not belong to the namespace you said.
so the question is
??what-lib??::thisbelongsto
i hope that helps...

hi, Stephan, thanks for respon

hi, Stephan, thanks for response
i still can not figure it out .actually all i want is just to use a new solver i download on the website.i find some tips in the user's guide, but it does not tell me how to creat my own solver and how to use it specifically. i am just a beginner,so could you teach me how to do it. maybe you method is better^-^

kind regards

Hi Wang please send me the

Hi Wang

please send me the solver u r tying to compile. I will give it a try on my system and see whether it works.

hi,

tha fact is that i have compiled the predefined solver,say icoFoam, i end up with the same errors, but i can run FoamX, and follow the cases in the user's guid without any bugs. so i think the solver is good .maybe the way i compile the solver is not correct, maybe something is wrong with my installation,and i fail to install some important files .so i am a little bit lost

i will send you the solver by eamil

many thanks ^_^

Hi, feng wang. I

I will also give a try. Send me the link.....

Hello Feng,

I would appreciation if your can send me the links for the solver and tutotial file for FSI.

hi a a saha

this is the link of the sovler and it also involves two particular case for the sovler.

Kind regards

Helllo Feng,

The link is not available in your post. Can you pl. repost the link again.

Hi Feng! Which Version of O

Hi Feng!

Which Version of OF are you using? I guess 1.4.x

The sources on that page currently only work with 1.3 and definitly won't compile on 1.4

Bernhard

Hi Bernhard! i am using 1.4

Hi Bernhard!

i am using 1.4.1. actually i want to install 1.3, but i can only download 1.4.1 from the wenbiste of OF.

all the best

1.3 is available at http://sou

Hello, I am trying to compi

Hello,

I am trying to compile a modified simpleFoam solver. But when I tried to run wmake an error comes out stating that:
"/usr/bin/ld: cannot find -llduSolvers
collect2: ld returned 1 exit status
make: *** [/home/USR/OpenFOAM/USR-1.5/applications/bin/linuxGccDPOpt/simpleConvergenceFoam ] Error 1"

The Make/options file is exactly the same as in OpenFoam.

I would appreciate if you could give me some advice.
