Floating Point Exception

Asked by Benedikt Maier

Dear experts,

once more I've come across some issue generating the single top + higgs process with aMC@NLO. I used the new MadGraph5 beta4 version to generate:

set group_subprocesses Auto
set ignore_six_quark_processes False
set loop_optimized_output True
set gauge unitary
set complex_mass_scheme False
import model loop_sm
define j = g u c d s u~ c~ d~ s~
define p = j
define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
define tt = t t~
define bb = b b~
generate p p > tt h bb j $$ w+ w- [QCD]

With some minor changes to the nominal run_card and param_card.

Now I got this error:

Hi,
can you try removing the content of the SubProcesses/trapfpe.c file?
Just leave it empty.
Some FPEs can occur in the code, which however are harmless.
Let me know,
Cheers,

Marco Zaro
