Summary0000843: Optional compress output for 'rawSurfaceWriter' (patch attached)
DescriptionAdd an option for compress output to the 'rawSurfaceWriter', similar to the format option in the 'ensightSurfaceWriter'.

Patches with the required changes to the source code and the example 'sampleDict' are attached. The code was tested in an modified solver and works as expected.

Is there any way to include the provided patches?

Or is the bug-tracker the wrong place for this kind of improvements to OpenFOAM?

Best regards,
