Hello,

I am meshing a wind turbine as part of a tutorial that I'm doing. The tutorial was originally written for v3 I think (in 2017), and I am adapting it to v10, this involved only minor changes so far like the surfaceFeatureExtract-> SurfaceFeatures dict, but It seems there's some other syntax issue here. The syntax in the mesh making bash file is as follows:
_______________________________________
(to rotate the 'rotating region')
transformPoints -parallel -rotate '((1 0 0)(0.993572 0 0.113203))'

(to transform the overall mesh from mm to m)
transformPoints -scale '0.001'
______________________________________
which results in the following errors in the log file (respectively)
___________________________________
[0] --> FOAM FATAL ERROR:
[0] Invalid option: -rotate
[0]
[0]
FOAM parallel run exiting

and

--> FOAM FATAL ERROR:
Invalid option: -scale

FOAM exiting
_____________________________

Can't see where the obvious syntax errors here are, if they point out to anyone, let me know. Thanks

if I do a quick:

grep -r transformPoints /opt/openfoam10/tutorials

then I get the following:

/opt/openfoam10/tutorials/compressible/rhoPimpleFoam/RAS/aerofoilNACA0012/Allrun:runApplication transformPoints "scale=(1 0 1)"
/opt/openfoam10/tutorials/compressible/rhoSimpleFoam/aerofoilNACA0012/Allrun:runApplication transformPoints "scale=(1 0 1)"
/opt/openfoam10/tutorials/heatTransfer/chtMultiRegionFoam/coolingSphere/Allmesh:runApplication transformPoints "scale=(0.01 0.01 0.01)"
/opt/openfoam10/tutorials/incompressible/pimpleFoam/RAS/ballValve/Allrun:runApplication transformPoints -pointSet ball "Rz=-45"
/opt/openfoam10/tutorials/incompressible/pimpleFoam/RAS/elipsekkLOmega/Allrun:runApplication transformPoints "scale=(1.6666 1 1)"

which does suggest that you've got the syntax wrong ... or rather, that it has been updated since v3. Try using the examples above to rewrite. Good luck.

I would also add 2 more tips in addition to Tobermory's one:

transformPoints -help

And

foamInfo transformPoints

Are also good ways to get information about an utility and how to use it.

Cheers,
Yann

Those are very handy features that I wasn't aware of, thanks! Will be sure to use that with other syntax issues in future.
