Hi everyone!
I m an undergrad interested to obtain a solution for a ram air parachute/payload system....while it is pitching up under aerodynamics forces... but for a partcular time instant.. it takes a lot of time to reach steady state.... is there some way by which i can incorporate unstady effects.... can Fluent do that?? waitin for a reply Yogesh babbar pec, chd |

Hi, This site may be of interest to you. It is the only site dealing with parachutes. The method used here is finite-element. Get a galarkin-based code for it. You can try Rheolef for it. You can try using Fluent deforming mesh feature but it will be a unsteady feature. Regards A.S. |

Hi Everyone,
I am interested in performing a CFD analysis on A Ram air parachute in steady state..If anybody can help me out on the geometry to be anlysed.. I need to know the equations defining the surface of the various surfaces of cells of the parachute.. if possible... or any suggestions... for approximations thanks Yogesh Babbar |

Hi,
You can look into LS-DYNA. I have quite a few people using LS-DYNA to do this type of simulation. Pei-Ying Hsieh |
