UDF of flow over oscillating cylinder 2D case
1 Attachment(s)
Sir I am recent into the UDFs and trying to simulate the flow over the oscillating cylinder.The UDF for cylinder oscillation is
#include "udf.h" #include "dynamesh_tools.h" DEFINE_CG_MOTION(cilindro1,dt,vel,omega,time,dtime ) { vel[0]=0; vel[1]=10*sin(100*time); omega[1]=0.0; omega[0]=0.0; } But when i hook it with cylinder it give me error Warning: incorrect cg motion UDF cilindro1 on zone 12 (assuming no motion) I have attached my problem domain as well. My email address is imharoon1@gmail.com Regards Haroon |

I don't know it works or not. But it may be helpful. http://www.cfd-online.com/Forums/flu...r-problem.html Regards! |
Thanks
Sir It is just coincidence.I am trying to contact you the whole day but your cell was switched off.At last i have put my problem on the site and you are the first person who respond on that.
Thanks Regards Haroon |
hiii friends i am entirely new to using udf's in fluent. I have a cubical geometry, with two inlets on perpendicular adjacent faces. i have to implement udf to only one of the conditions.
i have two cases 1) parabolic velocity inlet ( space varient) 2) sinusodial velocity velocity inlet ( time variant) can any one pls send me the udf ( codes) ... |
