hello dear
i want to simulate water and nano fluid cu in a fcc lattice…water is base fluid and cu is a region (sphere or box)in the center of lattice (between water)
molecules are in the range of 1000 to 1500 and cu atoms are about 400 to 500
when it runs it shows this error"illegal lattice command"
does anybody know how to define lattice command of sphere…
