Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
Hello Nicola, I would try following. Define G4Region in your geometry to the logical volume where you want deactivate msc (good example: $G4INSTALL/examples/extended/electromagnetic/TestEm8 or the same microdosimetry). Instantiate any Physics List, define region "target", and use G4EmConfigurator in any part of you code before "/run/initialise" G4EmConfigurator* em_config = G4LossTableManager::Instance()->EmConfigurator(); G4UrbanMscModel* msc = new G4UrbanMscModel(); msc->SetActivationLowEnergyLimit(10*TeV); m_config->SetExtraEmModel("e-","msc",msc,"target"); Unfortunately, you need to repeat the last line for all particles of interest. Because the model is deactivated it is not important what model is used, I choose Urban model because it is standard one. VI
