AMIInterpolation and cyclicAMI have been superseded by patchToPatch and
nonConformalCoupled, respectively.
The motivation behind this change is explained in the following article:
https://cfd.direct/openfoam/free-software/non-conformal-coupling/
Information about how to convert a case which uses cyclicAMI to
nonConformalCoupled can be found here:

Class
|
|
Foam::functionObjects::cylindrical
|
|
|
|
Description
|
|
Transforms the specified velocity field into a
|
|
cylindrical polar coordinate system or back to Cartesian.
|
|
|
|
Example of function object specification to convert the velocity field U
|
|
into cylindrical polar coordinates before averaging and returning the
|
|
average to Cartesian coordinates:
|
|
\verbatim
|
|
cartesianToCylindrical
|
|
{
|
|
type cylindrical;
|
|
libs ("libfieldFunctionObjects.so");
|
|
|
|
origin (0 0 0);
|
|
axis (0 0 1);
|
|
|
|
field U;
|
|
|
|
writeControl outputTime;
|
|
writeInterval 1;
|
|
}
|
|
|
|
#includeFunc fieldAverage(cylindrical(U))
|
|
|
|
cylindricalToCartesian
|
|
{
|
|
type cylindrical;
|
|
libs ("libfieldFunctionObjects.so");
|
|
|
|
origin (0 0 0);
|
|
axis (0 0 1);
|
|
|
|
field cylindrical(U)Mean;
|
|
toCartesian true;
|
|
result UMean;
|
|
|
|
writeControl outputTime;
|
|
writeInterval 1;
|
|
}
|
|
\endverbatim
|
|
This is particularly useful for cases with rotating regions, e.g. mixer
|
|
vessels with NCC.
