UDF for FSI simulation

ppa381 · October 24, 2009, 02:34

Hello does anyone have any files or know of any websites or tutorials that would be of help for writing a UDF file for grid motion for a deforming mesh. I already read through the Fluent UDF manual and seen the example on the fluentusers.com site for oscillating membrane. I need to solve a problem for 2-way fluid structure interaction. I cannot couple with other programs so I must write a UDF, but it is very challenging for grid motion; I do not know C programming very well. Any help would be appreciated, thanks. (Model is a pulsating pressure through a tube)

Hi, I found out Ansys 13 can perform 2way FSI analisys coupling Structural solver with CFX (but not with fluent).

regards

Thanks Atze..... ansys uses FEM based...... but v r doing FVM based.... fluent is giving correct results.... but i came to know that fluent has fsi feature ( c file menu n go for fsi mapping ) but we need to use UDF.... so anyone knowing abt this plz reply
