UDF-file for transient analysis
1 Attachment(s)
Hi,
I am trying to do transient analysis. the attached file shows what I want to write at UDF file which is temperature versus time. for now I prepared the below C program: first, I am not sure the program is true. second, if its true why after interrupting its attached to program but its not work ( I know because the default value considered automatically by the Fluent during the analysis process). start the UDF file : #include "udf.h" DEFINE_PROFILE(Temp_Profile, thread, position) /* Temp_profile is alternative, thread is boundary, { face_t f; real x[ND_ND]; /* this will hold the position vector */ real y; begin_f_loop(f, thread) { F_CENTROID(x,f,thread); y = x[1]; F_PROFILE(f, thread, position) = (-9e-27*y*y*y*y*y*y)+(2e-21*y*y*y*y*y)-(2e-16*y*y*y*y)+(1e-11*y*y*y)-(2e-7*y*y)+0.0009*y+9.4751; } end_f_loop(f,thread) } any helps? thanks, |
