Hi everyone,

I have a case with moving airfoils to influence the flow. Since I am not actually interested in the moving airfoils but in their wake, I simulated the moving airfoils and probed the wake with a surface. My plan is to use the results as an input for future simulations at the inlet so I do not need to simulate the airfoils and to avoid a moving mesh. I was able to move the post processing files (surface via probe in OF-Format) files to constant/boundaryData/inlet for each time step and add the correct header (comparable to the example for timeVaryingMappedFixedValue, just for each time step I resolved).

Two questions arose to me:

1. Will OpenFoam interpolate the timesteps inbetween?

2. How do I handle the fact that the amount of points differ between the time steps? So far I used probed via a cutting plane surface. This results in the aforementioned different amout of points and thus in this error:

Create time

Create mesh for time = 0

Reading field p



--> FOAM FATAL ERROR:
Number of values (38623) differs from the number of points (38748) in file "./test_inlet_from_slice/constant/boundaryData/inlet/4e-05/p"

From function timeVaryingMappedFixedValueFvPatchField<Type>::che ckTable()
in file fields/fvPatchFields/derived/timeVaryingMappedFixedValue/timeVaryingMappedFixedValueFvPatchField.C at line 425.

FOAM exiting

I put a points file into the folder (from a random time step) of the inlet patch below the folders of each time step (caparable to the tutorial case in incompressible/simpleFoam/pitzDailyExptInlet). I could provide the points file for each time step though, I just have no clue how to make use of it).

Any help to solve this is appreciated. Since the flow is complex i cannot discribe it via GroovyBC though.

Sincerely,

Henning
