[Gmsh] R: Geometry modification on physical entities

Hello Alessandro,

Have a look at the enclosed file for an example of what Christophe was mentioning. Also, I don't understand what you are trying to achieve "from the command line". Is it that you generate geometry as a physical entity in one .geo file and want to rotate it afterwards ? If that is the case, I don't think this can actually work because there is no input argument that you could use from the command line to specify with Physical Entity you wish to transform. This at least will have to be defined somewhere in a .geo file.

I'm afraid this is not clear to me, how can I use this feature from command line? Thank you.

No, but you can get all the elementary entities making up a physical group using e.g. "Physical Line {tag}" (it returns a list), which you can then use in the transformation commands.
