Thank you, now it works.
Could you please explain what would be the difference between < Foo /> and </ Foo > termination?
Looking over the xml file, it would seem that the </ Foo > ending is used for sub-sections (like BC, Params, Solver Info, etc.) and functions (Initial values, etc.), while the < Foo /> ending is for scalar parameters.
The fact that the Body forcing uses the </ Foo > ending may not be surprising, since BodyForce is itself another function, however for the Noise forcing, it is only a simple scalar value that is being provided.

Thank you,
Oliviu

Hi Oliviu,

There is a typo in your noise forcing. Instead of <WHITENOISE/> it should be </WHITENOISE>.
Also, at the moment this setting for white noise does not evaluate the parameters (or any expression, unfortunately). Therefore, you will have to replace it by
    <WHITENOISE> 0.001 </WHITENOISE>


Cheers,
Douglas

Dear all,

The problem I'm facing is probably trivial, but I just cannot figure it out.
The simulation is simply a test case for an under-resolved DNS of a flow at Re=3000 inside a circular pipe, with 1D homogeneity along the flow direction, a body force to drive the flow and some white noise to stimulate transition to turbulence.
The problem is that the IncNS solver throws the following error: Cannot find element 'GEOMETRY'.
The config file is attached here.
Any advice would be much appreciated.

Cheers,
Oliviu
