(60fps) Getting Started: Dynamic mesh motion using Ansys Fluent with UDF

Basic introductory Computational Fluid Dynamics (CFD) simulation tutorial using Ansys
1. Creating a simple 2D geometry: a moving solid plunger rod and a deforming fluid container in SpaceClaim, set Share Topology property to Group and named selections for zones and edges
2. Generating a 2D triangular grid in Ansys Meshing, ensuring there are no contacts
3. UDF created in Microsoft Visual Studio 2017
4. Setting up a transient incompressible isothermal single-phase flow simulation, creating mesh interface, dynamic meshing settings: 2 rigid body zones and 1 deforming zone, smoothing and remeshing
4. Solving and autosaving every 0.02 seconds, enabling animation creation in CFD-Post via Workbench

[@karanshukla3434]

Can u please help me in doing the same in 3D ?

[@prathameshsahoo3172]

Sir the console is showing no version of visual studio found but i have vs 2022 installed

[@futuretech42]

Awesome.....if possible can u give atry on bullet motion through the barrel of a gun using dynamic mesh?

[@fadoobaba]

yes. define the mesh motion in the direction of bullet flight. to simulate bullet drop, use 6 DOF method. (search, tutorials are available on TH-cam)

[@shanwang8236]

sir, i'm learning the udf, there are some questions confused me long time. hope you can give me some advices.
the first question is the messaging passing macro like PRF_CSEND and PRF_CRECV is block conmunicating or non-block conmunicating?
the seccond question is the library of messaage passing in udf is same as mpi library?

[@alfaageng]

Is this tutorial still works if the rod change as nozzle that spray water?

[@enzoarnaldi3032]

that 's working ?

[@adityasai3672]

can you please share the udf code

[@ChimmyYe01]

#include
DEFINE_CG_MOTION(functionname, dt, vel, omega, time, dtime)
{
vel[0] = 0.0;
omega[0] = 0.0;

if(time 1 && time

[@moncefeladraoui1014]

Can you please share the udf that you used ?

[@ChimmyYe01]

#include
DEFINE_CG_MOTION(functionname, dt, vel, omega, time, dtime)
{
vel[0] = 0.0;
omega[0] = 0.0;

if(time 1 && time

[@AsifRaza-jt5go]

can you please upload a tutorial with a ship (free to heave and trim) and propeller also rotating as well?
