Fluent 12 & Nastran

Atze · February 21, 2011, 09:38

Hi,

I tried to use FSI MAPPING SURFACE comand in fluent to export forces and pressure field from Fluent to Nastran, but i got error. The Guide reports the 2 meshes have to be "spatially equivalent"; simple in closed flow (pipes etc..) but i have to analyse open flow (flutter on a 3d wing) and the field is very big

Can someone help me? Is there a method to couple Fluent & Nastran (maybe with udf) ?

Thank you

I saw a presentation last week that seemed to indicate EnSight (from CEI) and Fraunhofer SCAI's FSI-Plugin for EnSight could do exactly what you are looking to do here. EnSight gets the Fluent data and through the plugin creates pressure field for a Nastran input file. Seems that it will also work for Abaqus. If you are interested in this, contact me. Darin McKinnis (CEI) darin -at- ceisoftware -dot- com and I can get your more details.
