G4Exception

[Abi-12308]

Hi, I am trying to compile detectorSimulations_v10 using Geant4.10.7.p01 and I am getting this warning message:

-------- WWWW ------- G4Exception-START -------- WWWW ------- G4Exception : visman0202 issued by : G4Scene::CalculateExtent Scene has no extent. Please activate or add something. The camera needs to have something to point at! Add a volume. (You may need "/run/initialize".) Or use "/vis/scene/add/extent". "/vis/scene/list" to see list of models. This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------

As I tried adding detector system, I go this message below:

G4WT1 > -------- WWWW ------- G4Exception-START -------- WWWW ------- G4Exception : Analysis_W001 issued by : G4RootFileManager::OpenFile() File g4out already exists. This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------

I will appreciate any assistance. Thanks in advance.

That sounds like the compiling part works, as that is not a compiler error, but an error running the simulation.

The first warning that you get is exactly what it says. It seems you are trying to run a macro that visualizes a setup, but you haven't specified that setup at all.

The other warnings are saying that a file is already open. I don't know why you are getting these warnings, but they are warnings, not errors, so maybe everything is okay? What does the output look like? And what macro are you running?

[Abi-12308]

This is how the output looks like in the terminal:

-------- WWWW ------- G4Exception-START -------- WWWW ------- G4Exception : visman0202 issued by : G4Scene::CalculateExtent Scene has no extent. Please activate or add something. The camera needs to have something to point at! Add a volume. (You may need "/run/initialize".) Or use "/vis/scene/add/extent". "/vis/scene/list" to see list of models. This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------

For file-based drivers, use this to create an empty detector view:

I am running a macro, Heather and I modified to simulate a single solid SiLi detector. The histograms are also empty even when I run large events. See the attached[https://res-geo.cdn.office.net/assets/mail/file-icon/png/generic_16x16.png]Cedar.machttps://triumfoffice365-my.sharepoint.com/:u:/g/personal/aavaa_triumf_ca/EbvtR3xyBv5NjJlsIocBEqIBNzWUzn4obqJF59jXF0l0Mg. Though even with the spice.mac which is in the example_simulations gave the same problem.

Thanks you for you response.

You might want to check the discussion in #82 then if you are using the same macro.

Do the other examples (like the 60Co one) work for you though?

[Abi-12308]

Hi,

60Co example did not even ran.

Hi, is it possible to edit the "DetectionSystemPaces" file to have only a single solid silicon with no holders, then create a macro to run it? I need help with this.

Here's a simple vis.mac that should show something. As this is no longer your original issue, and there is no problem with the group source code, I suggest marking this issue as resolved and opening another issue (or just emailing) if you have further specific issues.
