Problem 2133

Summary:	Pressure or temperature dose not change in ConstructNewIdealGasMaterial
Product:	Geant4	Reporter:	Shoichiro Nishimura <nishimu>
Component:	materials	Assignee:	Vladimir.Ivantchenko
Status:	RESOLVED FIXED
Severity:	major
Priority:	P4
Version:	10.5
Hardware:	All
OS:	All

Description Shoichiro Nishimura 2019-02-13 12:43:53 CET

When G4Material is constructed by G4NistMaterialBuilder::ConstructNewIdealGasMaterial and either pressure or temperature is changed from STP, both pressure and temperature are set to STP.
This may be because faulty coding at file G4NistMaterialBuilder.cc, line 401,
 if(temp != STP_Temperature && pres != STP_Pressure)
I think it should be
 if(temp != STP_Temperature || pres != STP_Pressure)

Dear Shoichiro,

thank you very much for this post. You really identify a bug in material constructor. The fix is already integrated into Geant4 development version and will be available with the next public release/patch to Geant4.

best regards,
Vladimir
