Hi all,
I only have a basic understanding of ANSYS Fluent so please excuse if my question is simple. ![]() I am looking to simulate a capsule traveling within a pipe against a fluid flow of 0.3m/s. The capsule will start at 0m/s in the centre of the pipeline and then accelerate at 0.1m/s untill reaching the end of the pipe. The capsule will remain in the centre of the pipe the entire time. From the simulation I hope to produce lift and drag coefficents on the capsule and velocity/pressure/streamline data of the surrounding flow. I hage already modelled a 2D flow regime with the capsule removed using Boolean Subtraction. I've used a basic mesh with inflation around the capsule to start of with but I'll improve this once I get the thing solving. Can anyone point me in the correct direction of how to achive capsule motion?? Any links to tutorials or examples would be greatly appreciated. ![]() Thanks in advance. |

Hi,
search for dynamic or moving mesh tutorial. Basically, you need to include the capsule inside a moving mesh box and write an udf to let it accelerate. The other mesh sorrounding that moving box will be remeshed.
