hi im trying to make a transient solver in different angle of attack 5 10 etc.and i am kind a newbie. have been facing coding this process. I searched but I couldn't understand or find it.
I am leaving my code in here. It gives error.As; https://www.ozeninc.com/tech-tip-flu...text-file-udf/ for the steps in here. #Warning: no x, y or z points specified in profile foil. in addition I tried the path in here and it did not work out. I may fluent toread my code but it does not show me file on fluent. Code:
#include "udf.h" DEFINE_PROFILE(inlet_x_velocity, thread, position) { real x[ND_ND]; /* this will hold the position vector */ real y; face_t f; begin_f_loop(f, thread) { F_CENTROID(x,f,thread); y = x[1]; F_PROFILE(f, thread, position) = 270.0 -22*t.; } end_f_loop(f, thread) } |

what is t. in your F_PROFILE
if u want use Variable speed with time, you must specify time before loop t=CURRENT_TIME; |

The link you posted has title "Tech Tip – Fluent Profiles: A Text File as Your UDF", but that is misleading :it shows you how to do it without UDF.
So, what are you doing? The approach from the link, without UDF, using scheme? Or do you use your UDF? You have to choose...

"The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform" is NOT the error after compiling. It is the error after loading. To see compiler errors, look at your screen after you click "build". |
