Hi, everyone, I am having trouble in dynamic meshing of piston movement within a closed cylinder in a sinusoidal way in positive & negative x direction in ANSYS FLUENT. Can anyone please help me by providing the UDF for the same.
Please say that the udf can be used for interpreted or compiled way in ansys fluent. |

I have read those sections mentioned by you @jbo214 but stil cant get the actual procedure of interpreting or compiling the necessary udf here, & for that the boundary is not moving at all. I am attaching the udf here for 1 d piston movement in x direction. Kindly see if this is correct or not & tell me the exact procedure of implementing this udf in ansys to get the result.
The udf that i used is- #include "udf.h" #include "dynamesh_tools.h" DEFINE_CG_MOTION(piston,dt,vel,omega,time,dtime) { NV_S(vel, =, 0.0); NV_S(omega, =, 0.0); vel[0]=2; printf("\n"); printf("\n x_velocity = %g \n", vel[0]); } |
