nmake tends to be the compiler not being installed/set up, we'd usually get a load of other errors if the code is wrong. Having said that, if the code is grammatically correct then you can get some odd errors if it's not using syntax that Fluent is expecting. nThe dynamic mesh methods are covered in the documentation (manuals, videos & tutorials) and in (paid for) courses that we offer. Try the former first as they're free. n
