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.

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 2018-02-07 10:56 GMT-02:00 Oliviu Sugar <oliviu_sugar@yahoo.com>: 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.
