Assigning material properties to an interior volume

I want to assign the empty volume within a closed container to be a fluid and assign material propertied to this fluid.
I imported a closed 3D model that is made up of a number of solid parts contained within a closed chamber made up of a tube with end flanges. Each part comes in as a solid domain that I can assign material properties to. What I want to do is to create a domain from the empty volume within the closed container and assign material propertied to this domain so I can model heat transfer through the fluid in the container. I am not sure how to create a domain out of the empty space within a closed volume.
Is there a way to do this within COMSOL or within Solidworks?
Thank you

Hi
if its in the geoemtrical part you have your proble, you can "box" your model inside COMSOL and have COMSOl to generate the volume that way, but to get it meshed and usefull you must inlcude it in some physics, and "solid" is not very useful to model a fluid you need some CFD module or a combined FSI or conjugated heat floe NITF

Good luck

Paul,
To create solid domain from a closed surface, use
Geometry>Conversions>Convert to Solid
This will create solid domain and you can assign material properties to it.
