Hello together,

I'm quite new to OpenFoam and CFD, so I am currently trying to understand the OpenFoam Tutorials. Since I am going to work on a FSI problem I thought it would be useful to run the "HronTurek" tutorial with the icoFsiElasticNonLinULSolidFoam solver proposed by the openfoam extend version (I work with version 3.1.). The calculation took one week (I couldnt run it in parallel, because of a compilation error...), and in the end the flag did not move at all. After some seconds there was kind of a steady state solution reached.. I didnt change anything in the files, except the writing interval, due to a lack of memory space I dont think that the installation of the extended version didnt work out, because the "flappingConsoleSmall" tutorial with the icoFsiFoam solver worked out well...
Do you have any idea what could have been the mistake?

Thanks in advance!

Hello,

I've got the same problem. There are some changes in p, but vector U remains unchanged all the time in the fluid, so there is no deformation of the "flag" after filtering "Warp By Vector".
I would be very thankful for any help, because I need to do FSI simulation in my thesis.

Best regards,
Bartosz Żłobiński

Hello again,

I've finally done HronTurek with toolkit "Fluid-structure interaction" (http://openfoamwiki.net/index.php/Ex...re_interaction).
It contains tutorial, that works correctly.

Best regards,

Hello,

As I have written, it's better to use toolkit "Fluid-structure interaction". It works for me.

Hello again,

I've finally discovered, how to see flag deformation in HronTurek tutorial case of icoFsiElasticNonLinULSolidFoam (foam-extend-3.2 for me).

You have to do (in ParaView) Filters->Alphabetical->Warp By Vector and choose vector Vs.

Flag's mesh should then move.

Best regards.
