Hello,
I'm pretty new to this stuff.
I'm trying to make a v1.5 version to work in the current version of OpenFoam.

I updated the boundaries, so I get a mesh. Now I try to make the simulation running. I use the kOmegaSST -model to do this.
Im using inlet, outlet, walls, fan_half0 and fan_half1 to define boundaries.

For walls for k, Omega, and nut I use:

k: {

type kqRWallFunction;

value $internalField;
}


omega:
{
type omegaWallFunction;
Cmu 0.09;
kappa 0.41;
E 9.8;
value $internalField;
}
nut:
{
type nutkWallFunction;
Cmu 0.09;
kappa 0.41;
E 9.8;
value uniform 0;
}


The pressure jump is defined in p, I just tried to make the old version:


fan
{
type fan;
patchType cyclic;
f List<scalar> 2 (10.0 -1.0);
value uniform 0;
}


work for OpenFoam6.
The simulation told me to use JumpTable, so the list doesn't exist anymore.
I copied another definition for the jumpTable, which made the simulation working, but the pressure jump with the defined jumpTable was too high.

Can I somehow "translate" this list f into a jumpTable, which does the same?
In the example the pressure jumps from -6.3 bar to 0.5 bar after descending from -5.8 bar.
In my simulation w8i9th the copied jumpTable the pressure jumps from -37 bar to 5 bar after descending from -35 bar.

I figured the jumpTable defines the developement of the pressure here, Am I correct?

Regarding readability, I'm sry if the text is hard to read, due to me using the code in fluent text, but I didn't find the option, where u can set the code off, which other people use

Anyone any idea?

I don't really understand your questions,
Take a look at this pages:

1) https://www.openfoam.com/documentati...-jump-fan.html

Example usage:

Any progress?

I am sorry for not replying.
I made progress in taking another version of an implementation of an actuator disc, which matched my recent version of OpenFoam 5.0.
This versiuon uses the class rotorDisc, which calculates volumeForces and adds them to the flow.
I didn't try any further simulations with jumpTable.

@syntex, could you please provide a reference for what worked for you?

I used the class rotorDiskSoure stored inside fvOptions, this class adds force to the flux, and I manipulated the way the force was added for my simulation.
You need to define a fvOptionsFile inside the system folder to set some parameters which the rotorDisc class uses.
Have a look at the class, then you my be able to make sence of what to do.
rotorDiscSourceTemplates.c is the file, where the forces are calculated.
