Hi again,
I found a workaround that solved my immediate problem:
In the G4GDMLReadSolids.cc file I replaced the line
...
else if(attName == "lunit")
{
G4UnitDefinition::GetValueOf(attValue);
...
with
...
else if(attName == "lunit")
{
lunit = G4UnitDefinition::GetValueOf(attValue);
...
in the GenTrapRead()-method. This also seems to be what is done in the other XXXRead()-methods.
Thanks for spotting the problem. The fix will be included in the next patch release! |
Created attachment 665 [details] GDML-file and pictures. Hi there, I'm having trouble reading an arb8 shape from a gdml-file, using the executable built from 'examples/extended/persistency/gdml/G01'. It looks like the gdml-parser interprets the coordinates in mm, even though the lunit is specified as cm in the input file. I attached my gdml-file as 'test.gdml', as well as a picture of the geometry visualisation (geant_vis.png). The gdml-file was exported from the ROOT geometry package, and I attached the corresponding visualisation from ROOT (root_vis.png), just for comparison. The test.gdml describes an arb8 and a tube, and it looks like that the arb8 is scaled down by a factor of 10, when it is loaded into Geant4. Any help with this would be much appreciated.
