Hi

I am trying to simulate an internal mass source (inlet), by defining an inlet on a solid. However I keep on encountering an error, saying that I have defined a wall between two fluid cells.

Does anyone know what this means ?

Thanks

Hi Steven,

By internal mass source, do you mean it is surrounded by fluid? Inlets can only be specified on external boundaries.

Is it a 3D solid or is it just a wall on a surface. I think it must be a 3D solid.

I am using using a 3D solid, to model building column. Attached to this column is a fresh air duct.This fresh air duct is supplied from another floor.

I specified a wall Patch (with a boundary condition ) on a 3D solid column to model the incoming flow.

However I find that I get error messages stating that I have defined a wall between two fluid cells.

Is this the wrong approach ? What is the best way to model this problem ?

Thanks Steven

Hi Robin

By internal source I mean I am trying to specify a inlet (wall patch)on a 3D solid within the computational domain.

However I keep on getting an error message stating I have defined a wall between two fluid cells ??

Thanks Steven

Did you specify the solid as a cut-out solid in your domains form?

Robin

No just one solid
