New question #403514 on Yade:
https://answers.launchpad.net/yade/+question/403514
Hello,
In the past, I used Ubuntu 14.04 to install YADE(1.07.0) and built a model
which used material "cpmmat". It worked fine. But now, I used Ubuntu 16.04 and
install YADE(1.20.0) on it by the same way that using the command "sudo apt-get
install yade", and use it to run the same *.py code(model). It does not work
any more. If I use YADE on Ubuntu 16.04 to run the concrete example in
trunk/examples/concrete, it still work fine. I think may be the YADE source
code changed(from 1.07.0 to 1.20.0) and my model is incompatible with the new
one. The error information and my code is following. Can you give me some
suggestions?
