How can I extract slice and node for (each) observation wells? The input data contains x,y and z coordinates and I need to extract the corresponding node and slice in my 3d model.

Thank you in advance

Spatial Units panel -> Right click on Observation Points -> Export Observation Points. I typically export as .dat

Hi Adam,
Sorry, I wasn't clear in my question. I have x,y,z data and I want to convert them to observation points but Feflow asks for slice number. However, I do not know that for my points. And it seems like when I don't include slice number and choose "free x,y,z" it does not give me and error bar when I run the model. I don't know if the two are related but my suspicion is that Feflow requires slice numbers.  So the question is how do I extract slice number for an x,y,z point?

Observation points can be located at nodes/slices, or they can be freely placed. In the first case, you have to impose the node number/slice number. In the latter case, you have to specify the field containing the z-coordinates, while the field for the node number needs be set to [i]<no node>[/i] and the field for the slice number needs to be set to [i]<free xyz position>[/i].

The process variable value shown for free xyz positions is then derived by interpolation from the corner nodes of the element the point is placed in.

Thank you both for your help. It worked out.
