UDF saving data to a text file
Hello everyone,
I'm working on a case of particle injected into a flow and subjected to ultrasound radiation force. I then modeled this force as body force and I introduced it in fluent using Udf where the variable returned is named radforce. The problem is that I cant see this force in fluent console even if I add this line: Message ( force: %g\n ,radforce) ; I also tried to write force calculated data in a text file, but nothing works the text file which is in the same folder as the case and the data is empty. BODY_FORCE( ) { FILE *fp; real radforce; /*calcule of radiation force*/ if(NULL == (pf = fopen("data.txt","w"))) Error("Could not open file for append!\n"); fprintf(pf,"%e\n",radforce); fclose(pf); If someone has an idea and can help I will be really grateful. Thank you very much J |
Why fp appeared in the declaration section
FILE *fp; but pf is used in the following pf = ... fprintf(pf...) ? No error during compilation? |
Oh thank you Blackmask but it was just a typo when writing this message but the file is fp :)
|
actually the problem is in the compilation :(
