periodic boundary condition for 1000 mm tube

      Can I consider a periodic boundary condition for a receiver tube( through which water flows) so that a 1m tube can be taken as a repeating pattern of a 100 mm tube. I want that I only have to model a 100 mm tube instead of a 1m tube by using a periodic boundary condition which could get the results for 1 m tube geometry. This will help me save some computational time and will be able to run with the available system.

      Kindly give some insight on its feasibility if possible.

      Hi,

      Tube can also be model as 2D axisymmetric, this also help to reduce computational time.

      Periodic boundary conditions are used when the flows across two opposite planes in your computational model are identical.

      For more details on periodic boundary condition, please refer user's guide: 7.4. Boundary Conditions (ansys.com)

      Please have a look at the video on periodic boundary condition:

      Hope you find this useful.

      Thank you
