Exhaust proble,
« on: December 06, 2010, 04:38:09 am »

I''''m new on the forum. I''''m from Switzerland and working on fire modelling for my job.

I''ve a problem. I''ve made a simulation with an exhaust surface at the top of the room.
I think there''s a problem because where I run the simulation I can''t see the smoke going through the exhaust surface.

Ho do you build exhaust surfaces?

Thanks a lot,

When smoke is drawn into an exhaust surface, it should simply vanish. You can verify that the surface is pulling air as expected using a velocity slice plane.

Are you able to post a PSM file, an image, or some working portion of the FDS input so we can see what you mean?
