I need to solve flow past obstacles on the unbounded domain at Freefem. Is it possible? How can I write?

Thank you

I think a reasonable approximation is that you use a sufficiently large truncated domain for your calculation. If you need a semi-infinite domain, you could use a coordinate transformation to map a semi-infinite domain to a finite one which can be handled by FreeFem.
