When I transfer results from fluent to static structural I get and error if I have applied multiphase.

I have done the same simulation, with static (singlephase), transient (singlephase), transient (multiphase) and the first two pressures were well exported to static structural, but when I use multiphase, It says that no pressures are found on the face selection

How are you transferring? Can you add a screenshot?

[pv00170]

I have first created the workflow for Multiphase and then copied it, and modified it for doing a Single phase.

I have also included the Static Structural screenshot in which for the Multiphase it says "No pressure data was found on the selected surfaces".

I think the workflow works, since the SinglePhase is just a copy of the Multiphase, I have just changed the VOF.

If you open up the Fluent solver have you got pressure data in the model? Ie has it run? 

[pv00170]

Yes! Both Fluent models got pressure results.

The only thing is that Static Structural doesn't read the results when using Multiphase.

I don't know if its a problem I just encounter.

Hi,
Please try with changing the 'interpolation type' from 'Mechanical based Mapping' to 'CFD results interpolator'. 

Mechanical-Based Mapping only imports normal pressure.

Please refer Using Imported Loads for One-Way FSI (ansys.com) for more information.

Hope this helps you!

It says:

CFD Load Transfer Summary

-- ERROR -- Cannot calculate force. Variable 'Mixture.Volume Fraction' does not exist.

Hi,

It may happen due to fluent results files saved in HDF5 (.dat.h5) format and we are looking into it. As a workaround, please change the default file saving option to legacy format (.dat/.dat.gz) and then try to import load.
