Hi,
it is a 2D vertical model. The IDW seems to work but i found out the file i am using to import the data is empty. So the actual problem is the export of the initial values into the *.trp file and not the import. Sorry, just found that out now.
Why is the file empty if i set any initial hydraulic head and export it by assign -> database -> hydraulic head -> export time constant data?
Thanks a lot for your help
