When I followed the exmple in Chapter 5 of the guide book “Computational Hydrology I:
Groundwater Flow Modelling”, I found that I can’t set initial conditions on mesh nodes using Dataexplorer, for I can’t find the buttom “DIRECT Conditions” after I have right-clicked the mesh file.the pic is my computer screen capture.
(Pardon for my poor English)
The screenshot above shows that you use the DataExplorer version 6.3. As far as I remember the direct conditions functionality is only in the old version 6.0 of the DataExplorer. The book should contain a link to download the old version.
