UFO Error: particle names in UFO models

Hi,
actually the output that you are showing is not from an UFO model. It seems that you tried to create a certain model (with anomalous triple couplings?), but the model file ( /home/packages/workwhizard/share/whizard/models/SM_aCTGC.mdl) has been created independently, either by hand or by means of the (deprecated) SARAH or FeynRules interfaces. There is no corresponding executable of our matrix element generator to generate matrix element code ( /home/packages/workwhizard/bin/omega_SM_aCTGC.opt: Command not found). Having said that, from the output this was an incompletely generated model not created by means of a UFO input. For a UFO-based generated model, please follow the steps in Sec. 17.3 of the WHIZARD manual.
Cheers,
    JRR (Juergen)

Hi user1905,

welcome to Whizard. From the error message, it appears that you forgot to add '(ufo)' in
the model statement

   model = SM_aCTGC (ufo)

because Whizard tried to load a hardcoded model "SM_acTGC", which doesn't exist.

Cheers,
-Thorsten

I initiated fresh. the .sin file is as follows,

model = SM_aCTGC(ufo)

process eeww = e1, E1 => "W-", "W+"
process dec1 = "W-" => e1 + e2, N1 + N2
process dec2 = "W+" => u + c, D + S
!unstable "W+"() { ?auto_decays =true}
!unstable "W-"() { ?auto_decays =true}
unstable "W-" (dec1)
unstable "W+" (dec2)
compile

sqrts = 250 GeV

integrate(eeww){iterations = 3:100000:"gw", 5:30000:"w", 5:10000}

n_events = 1000000

sample_format = lhef
$lhef_version = "3.0"

simulate(eeww)

The error i received is,

Thanks Juergen Reuter, that solved my question.
