    Can you change the model size range in HFSS ?

    HFSS size hi i am simulating a stripline filter in hfss. the lenght of my model is around 11inches. whn i run the simulation i get a warning sayin that the dimensions of the model exceed the hfss model size. can the model size range be changed. will it affect my sim results
