Hello, nTo solve a Fluid problem in Fluent, your geometry needs to be the 'fluid' region. So, if you have this Fluids region in your Maxwell geometry already, then you can use this 'Fluids' geometry. nAlso, you cannot use the geometry directly in Fluent. You will need to create the mesh file based on the geometry. Fluent can then read this mesh file.nThank you.nKarthikn
