New question #693574 on Yade:
https://answers.launchpad.net/yade/+question/693574
hello,
i try to creat pfacet using both "append pfacet directly " and
"pfacetCreator3", both of which give error "'ScGeom' object has no attribute
'connectionBody'" . and i notice that it also shows error below.
File "/usr/lib/x86_64-linux-gnu/yade/py/yade/gridpfacet.py", line 110, in
gridConnection
i=createInteraction(id1,id2)
RuntimeError: Interaction #0+#1 already exists.
i cant solve it.. below is my code.
