hello everyone!
Can anyone please give me some tutorials (or their link) related to 3D UDFs. All the examples given in fluent tutorials are in 2D. Thanks in advance! Regards Ankit Verma aviitkgp1@gmail.com |

I have read many examples of 2D UDFs, but there's no example of 3D UDF given in fluent tutorial.
I wrote a 2D UDF to vary contact angle along x axis at the bottom surface. I am not sure whehter it would work for 3D as well. The UDF is : #include "udf.h" DEFINE_PROFILE(contact_angle,t,i) { real y[ND_ND]; real x; face_t f; begin_f_loop(f,t) { F_Centroid(y,f,t); x=y[1]; F_PROFILE(f,t,i)=90-(1700*x); } end_f_loop(f,t) } x varies from 0 to 0.05 y varies from 0 to 0.01 z varies from 0 to 0.02 The contact angle is defined at y=0 and does not change with z direction. --Ankit Verma |
