Hi,
    I am trying to simulate simple fluidflowthrough pipe. so I model a pipe using solidworks. But when Iopenit in Flow work , a 3-D Cubical volume is consideredforcomputational domain. I have chosen the "internal" optionbutstill not able to get rid of the outside volume. Automatic meshiscreated for the whole cubical volume.
I would appreciate any kind of help.

Thanks,
