Using ODEsobol with paralell_eval=T: function cannot use global variables

[egoult]

Apologies if there is an obvious solution.
I am attempting to use ODEsobol to analyse a function, which uses global variables inside the function. It works okay if parallel_eval=F, but when running in parallel it gives the error "object 'Extvariable' not found".
I cannot define the Global variables inside the function being analysed, so I am unsure how to avoid this error.
Thanks

Is it possible to avoid global variables and define it as a parameter?
We start different workers in parallel which don't know about global variables. It works in non-parallel because of the R scoping rules.
