Thickness of 2D discrete feature

Hi. Simple question but havn't found description in FeFlow documentation. Does geometry.thickness of a 2D discrete feature indeed refer to thickness of the feature, e.g. thickness of fault zone? and when using Hagen-poiseulle law, what is geometry.thickness used for, considering that hydraulic aperture is also a parameter?

Regards Christian

Hi Christian, the first question can be answered with yes. The thickness can be also considered as the “third dimension”. I am not sure about the second question. I did not use Hagen-Poiseuille for a while. I need to check the FEFLOW book. If I remember correctly, it is written in Chapter 4. I would expect that one parameter is used for the geometry and the other for resistances. If you are in doubt please contact the FEFLOW Support: https://www.mikepoweredbydhi.com/support. At the moment, I am at the airport and next week not in the office.

Thanks. Have a nice trip. Christian

Björn, you are right: Thickness is used for geometry, aperture to calculate roughness.

Thanks Peter.
