ANSYS FLUENT – Dynamic Mesh

In this website, we share a tutorial about Dynamic Mesh, that’s easy and you can find the files in the link below.

It is important that you are familiar with UDFs (User Defined Function) in these videos you can see a brief explanation of this topic. In addition to this, if you have problems to compile the UDF file, please I suggest you should see this video before starting this tutorial: Compilated UDF

  1. Hello CFD Ninja, I’m do my thesis with a air valve, this valve expel air trough a short section where the element regulator of expulsion is a flotator, i need simulated this case, but i cant create the dynamic mesh.

    Can you help me please ..?

  2. i want dynamic mesh udf file. could you send to my email

  3. Hello my friend. I wonder if there is possible to create a dynamic mesh with 3D geometry.. I’m trying to simulate the flow in a stirred tank..

    Regards

  4. HI CFD NINJA…I AM TRYING TO SIMULATE THE MOTION OF A WATER(BOTTLE) ROCKET
    CAUSED BY ITS ON THRUST(EJECTION OF WATER & AIR) AND GRAVITY USING EXPLICIT VOF ,DYNAMIC MESH AND 6 DOF UDF.WITHOUT 6DOF MOTION THE PROBLEM CONVERGED EASILY BUT WHEN I ACTIVATED MOTION(DYNAMIC MESH & 6DOF),PRESSURE INSIDE BOTTLE BECAME TOO HIGH(EXPONENT POWER OF TENS)..WHAT COULD THE PROBLEM BE!!..ANY HELP WOULD BE GREATLY APPREACIATED…TQ

  5. Hi sir. I do this project with another geometry (a tank 50m*30m) but in dynamic mesh I had an error. The total mesh is not remeshing and the ball fall down in the rigid mesh and not reformed mesh and remesh.. Can help me?? Thanks

    • Hi friend, please check that Remeshing option is enabled. Regards

      • It is enabled but not work. In the geometry I have 2 surface. One surf is between ball and interior line and other surf is other face. Is the not remeshing refer to it???

  8. H sir. I do this toturial with another diameter 50*30 m. I do same introduction about your toturial. I had an error. Amg solver error and turbulent viscosity. Help me please

  10. Hello CFD Ninja, I’m trying to simulate this same problem using Fluent V18.0 but it seems like it does not reproduce well the behaviour of the cylinder.
    With this version I dont need to use UDF functions, can you help me?

    • Hi friend, UDF function help for faster analysis, however you can insert data without it, remember that you need the inertial moment for your cylinder otherwise the behavior will be different. Regards
