Leaks of gaseous fuels are often the origin of an explosion or fire threat simulated by FLACS.

What are leaks?
Whether you want to model a high momentum jet releasing pressurised gas into the domain or an extraction fan sucking gas out of the domain, they are both de...

How to define a point leak
A point leak is a leak released from a single control volume and where the leak area normally is smaller than the area of a control volume face. If you d...

How to define an area leak
An area leak is a release extending over multiple grid cells and where the leak area is normally greater than the area of a single control volume face. ...

How to model a fan in FLACS
You can use a fan leak to add a fixed momentum to the gas in the defined location without neither adding or removing any mass from the domain. A practical s...
