Hi everyone,
referring to this youtube video https://www.youtube.com/watch?v=fbaV_knzzks
which is a part 1 tutorial for a dynamic mesh problem for a piston and reed valve, could you please explain the utility for the fluid_valve_prisms zone and the fluid_stationary_prisms zone ?
One more question, why defining the gravity force on the piston in UDF. Why not defining a global gravity force in operating conditions ?
Thank you in advance.
In ANSYS Fluent, resolve deforming mesh and zone definition issues by ensuring a proper setup. First, verify the mesh suitability for deformation, especially in relevant regions. Activate the deforming mesh option in the solution setup, specifying the correct deformation model. Clearly define zones, specifying deforming and stationary areas and ensuring proper connections. Set appropriate boundary conditions, paying attention to motion for moving or rotating boundaries. Check solver settings related to dynamic mesh and deformation, ensuring compatibility. Provide accurate initial conditions for deforming zones, including velocities and temperatures. Use Fluent's monitoring tools to visualize mesh deformation during simulation, aiding in issue identification. Careful review and consistency in zone definitions, boundary conditions, and solver settings are essential for a successful simulation.
