Hi this was raised in 2009, but I've a colleague with the same problem - trying to get overlapping variable z shapes to work for a dam embankment failure.
The overlapping variable z shape regions are in separate shapefiles that are meant to be triggered one after the other. That is, the Trigger Value of the first v_zsh is 1 hour, with a Period of 0.25, and then the next Trigger Value is 1.25, etc . However what happens is the embankment doesn’t do anything until the final v_zsh (at 3.5 hours) and then fails the whole way to the bottom.
There is also a warning: type (1 2 3 or 4 randomly) WARNING: Variable Z mismatch zCur == (number), but z1 = (number), forcing zCur=z1.
I have tried them all in one shapefile, and get an error*
Does anyone have an experience with this? Does the order that the v_zsh are read in matter?
The next approach is to conceptualise the failure without having the shapefiles overlapping - but we're still interesting if anyone has got overlapping variable z shapes to work.
Thank you.
