Hello,

I want to investigate the heat transfer effect of ultrasonic vibration. For this purpose, I have formed a basic fluid domain like smooth tube with L=500 mm (3D). I want to apply ultrasonic vibration on the middle section of this domain and I splitted the surface with the help of face split tool. After that, I have meshed fluid domain, clasically.

 

After that, I have formed a UDF code for solve the ultrasonic vibration in ANSYS Fluent. In this point, I have a question to you. How I identfy the UDF code as a boundary condition for fluid domain wall? Also, is it required using the dynamic mesh althoug there is no any solid?

Thank you for information.

Best regards.
