runPrimal for FSI simulation

[erkhans]

Hello.
When I use runPrimal in the transient simulation, it creates only one .f5 file. How can I make it to create more .f5 files to see the deformation? I have attached the runScript.txt file.

You can use the DAFoam's built-in f5tovtk util to convert f5 to vtk.

Thank you, Professor. The problem is that when I use "runPrimal" for 2-way FSI, it does not deform the structure. How can I enable it?

[friedenhe]

OK, the current version does not support transient FSI...

[erkhans]

Thank you, professor. How do I enable it, if I do static FSI simulation?

[friedenhe]

Did you mean to "enable structure deformation in paraview post-processing"? We covered this in the 2022 workshop. Check the slides and video.

No, I mean when we do aerostructural optimization, the structure deforms. But when we do FSI simulation with runPrimal, the structure does not deform. It just shows the contours. I have attached the screenshot. How I can make the structure deform during FSI simulation?

[friedenhe]

Can you elaborate on how do you check if the structure deforms? Can you reproduce this issue with the MACH-tutorial wing case?

When I visualize the results from optimization (using opt) in paraview, I can see the deformations of structure as in the first picture above. However, when I visualize the results from FSI (using runPrimal) in paraview, it just shows the loadings on the structure, and there is no deformation of the structure. It is shown in the second figure above. But, when running the FSI simulation, there should be deformation. What needs to be done to make the structure deform in FSI simulation just like in an optimization simulation? Could you, please, help me with that? I have also attached the runScript.
