Re: Question No Model found for Hadronic Interaction using G4EnergyRangeManager (Stephanie Hickford)

HI. I'm running Geant4.8.1 and I'm trying to set up hadronic processes for particles having
energies between .1 and 600 GeV. I occasionally get the following error when I'm running a shower
of several thousand protons.
G4EnergyRangeManager:GetHadronicInteraction: counter=1, Ek=24.565401, Material = Pure Aluminum, Element = Aluminum
*0* low=0, high=20
In src/, line 123:
===> GetHadronicInteraction: No Model found
Unrecoverable error for:
 - Particle energy[GeV] = 0.024565401
 - Material = Pure Aluminum
 - Particle type = neutron

*** G4Exception : 007
      issued by : G4HadronicProcess
ChooseHadronicInteraction failed.
*** Fatal Exception *** core dump ***

*** G4Exception: Aborting execution *** Aborted -------------------------------------------------------------

It seems only neutrons generate this error. I have inelastic and elastic process set forhe a range which includes the energy mentioned above yet there's and error. When I take away upper and lower bounds it says models overlap and it doesn't like this. How can I correc this problem?

Here is my hadronic's list code for neutrons.


//Elastic model and process for neutron G4HadronElasticProcess* thenElasticProcess= new G4HadronElasticProcess();

thenElasticProcess->AddDataSet(new G4NeutronHPElasticData);

G4LElastic* thenElasticModel=new G4LElastic();


G4NeutronHPElastic* theNeutronHPElasticModel=new G4NeutronHPElastic();




//INelastic model and process for neutron

G4HadronInelasticProcess* NeutIneProc=new G4NeutronInelasticProcess();

NeutIneProc->AddDataSet(new G4NeutronHPInelasticData);

G4LENeutronInelastic * NeutInModel=new G4LENeutronInelastic();




pmanager-> AddDiscreteProcess(thenElasticProcess);




pmanager->AddProcess(new G4UserSpecialCuts(),-1,-1,2);
