Volume extract

How can I create a volume extract model of the inside of a building? In other words, fill the entire building with jello, using the building as a mold, and then pull out the Jello in the shape of the interior volume.

I need this to be able to extract the air volume to perform CFD (computational fluid dynamics).

Thanks,
Justin

Hi Justin,

 

If there are rooms placed in the model you can extract their area's for your fluid dynamics, room are usually placed by the architects.

 

If you are using or creating an MEP model then you'd be creating and using spaces.

 

You can create spaces based on Architectural Rooms.

 

There are rules for creating rooms and spaces and you'll need to think where you want the areas to report from eg, finish face of the walls or centre line of the walls etc, as this will affect your fluid calculations and performance.

 

Remember to include all spaces such as ceiling and floor volumes under raised floors as typically the architects will not have provided spaces or rooms for these areas.

 

Hope this helps

Thank you! The type of structures I will be doing work for are parking
garages. Large openings could exist in the exterior of the building in
certain areas that communicate directly with the outside atmosphere. If I
do a room area will the large opening in the exterior walls cause problems?
If yes, are there any workarounds for this?

The openings will not usually cause the Room or Space to "bleed" and lose its boundary, unless it is at the floor level ( no sill). In that case, use a Room Separation Line to "close up" the gaps for the Room boundary.

Hi

 

1. Have a mass, or overall volume.. ( A cubic meter )

2. all walls, floors etc ( B Cubic meter )

 

You can export the entire model in CAD, Solid, and in CAD

use " Volume " command to get volumes i.e B Cubic Meter

 

Simply A - B will give you the volume which you need.

 

Cheers !
