fail to handle expression

Post by Wenxing » 7. May 2017, 16:20

Hi Florian,

Sorry for disturbing you..
In my model, all is okay when I making ufo with sarah in mathematica( with no error or warning), but after I generate and output a process in madgraph, it says,


fail to handle expression: {...some long expression...}, type()=<type 'str'> .

I don't know where is wrong, is my model (some 331 model ) too complicated to be handled?

Best wishes~

Sorry, I have no seen something like this before.
You should check if there are some log files which give more details.

Cheers,
Florian
