# binField: coordinate system is read but not applied

### Summary

In the binField function object, it is possible to define a coordinate system. This coordinate system seems to be read since it is printed at solver startup but the values reported in the forceBin.dat file are not updated to use this coordinate system.

### Steps to reproduce

Define 2 binField functions: The first one using the case coordinate system:

```
binField_caseCoord
{
type binField;
libs (fieldFunctionObjects);
fields (force);
patches (motorBikeGroup);
binModel singleDirectionUniformBin;
decomposePatchValues false;
writeControl timeStep;
CofR (0 0 0);
binData
{
nBin 10; // output data into 20 bins
direction (1 0 0); // bin direction
cumulative yes;
}
}
```

Second one using a user specified coordinate system:

```
binField_customCoord
{
type binField;
libs (fieldFunctionObjects);
fields (force);
patches (motorBikeGroup);
binModel singleDirectionUniformBin;
decomposePatchValues false;
writeControl timeStep;
coordinateSystem
{
type cartesian;
origin (0 0 0);
rotation
{
type axes;
e1 (0.9848 0 0.1736);
e3 (-0.1736 0 0.9848);
}
}
binData
{
nBin 10; // output data into 20 bins
direction (1 0 0); // bin direction
cumulative yes;
}
}
```

Both functions use a force field computed by a forces function object:

```
totalForces
{
type forces;
libs (forces);
executeControl timeStep;
writeControl writeTime;
log yes;
patches (motorBikeGroup);
CofR (0 0 0);
rho rhoInf; // Indicates incompressible
rhoInf 1; // Required when rho = rhoInf
writeFields yes;
}
```

### Example case

A test case based on the motorbike tutorial is attached to reproduce the bug. motorBike_binField_bug.zip

###
*bug* behaviour?

What is the current The coordinate system seems to be properly defined according to the solver output:

```
forces totalForces:
rho: rhoInf
Freestream density (rhoInf) set to 1
Not including porosity effects
Fields will be written
binField binField_caseCoord:
Activating a set of single-direction bins
Employing 10 bins
- cumulative : 1
- decomposePatchValues : 0
- direction : (1 0 0)
binField binField_customCoord:
Setting co-ordinate system:
- type :
- origin : (0 0 0)
- e3 : (-0.173603 0 0.984816)
- e1 : (0.984816 0 0.173603)
Activating a set of single-direction bins
Employing 10 bins
- cumulative : 1
- decomposePatchValues : 0
- direction : (1 0 0)
```

However, both binField functions report the exact same values in the forceBin.dat files.

###
*correct* behavior?

What is the expected forceBin.dat files should report different values, as the force field should be expressed in a different coordinate system.
