About dynamic mesh and workbench

      Hello everyone,

      I would like to ask 2 technical questions about Ansys Fluent.
      1) Is it possible to use the in-cylinder feature at two different zones in a single model with different compression properties (stroke, angle, etc.)?
      2) Can two fluent models be dynamically coupled (two-way information exchange) in Ansys Workbench?
      I would be very happy if you could answer my questions.

      1) Only one set of in-cylinder properties can be defined at a time in Fluent. To have 2 different piston-like motions, you can use UDFs to define your motions.

      2) Yes, Systems Coupling can have 2 Fluent Participants. However, this would only apply to thermal analyses. Fluent cannot pass Displacement or receive Force variables.
