AttributeError: 'MultiPolygon' object has no attribute 'exterior'

Hey Guys,

I have a problem with calculating the Hazard Curve of a SimpleFault. The terminal output is like:

AttributeError: 'MultiPolygon' object has no attribute 'exterior'

I've done some other calculations with different FaultGeometry Specs and it all worked fine. Additionally I run it on different machines but the Error remains the same

my input-files look like that:

job.ini: http://pastebin.com/Y3NDHDiD

source-model: http://pastebin.com/uBVqgJKv

For the ground motion I used the model of AkkarBommer2010

Do you have any hints how to solve the problem? 

The polygon vertices are ordered into one line, so the error prompt doesn't make any sense to me.

Thanks for your help,

Martin

It is good that you are sending us the files you are using, since in this way we can reproduce your computation.

For the future, please zip all the files (including the logic tree files) in a single archive and send it to us.

I will leave the answer to our hazard scientists, since it looks like a hazardlib error due to some problem

with the source geometry.
