It is not recommended to use global variables or external objects in Modelica functions. Instead, pass them as additional parameters.
Reasons - Global variables break the mathematical function property that a function called with the same argument values always return the same results - Modelica compilers can reorder function calls by symbolic manipulation. If you use global variables, bugs can appear. - you models become less understandable with global variables.

Hi, does anyone know if it is possible to define global variables inside a Modelica function? Using the inner/outer concept does not work for functions, or? Does anyone have an idea how I can solve the problem of accessing environment variables inside a function without having to send these variables as input arguments to each function?
