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)|
You probably know that (faulty) programs can behave very differently, simply by adding an innocent line of code to the source. This causes the executable to be stored differently in memory and, bingo, if your program overwrites memory - completely unrelated to that extra code - it may now overwrite a part of the memory that suddenly crashes your progam or causes it to behave very differently. I believe, your issue is exactly that and has nothing to do with your field implementation.
You should ask, why:
> Step# X(mm) Y(mm) Z(mm) KinE(MeV) dE(MeV) StepLeng TrackLeng NextVolume ProcName > 0 -0.952 -0.618 3.74 0.174 0 0 0 ion_cham_layer_param_phys initStep > 1 -0.756 -1.95 6 0.174 0.000382 2.64 2.64 ion_cham__sens_phys Transportation > 2 -0.756 -1.95 6 0.174 0 -1.13e+25 -1.13e+25 ion_cham__sens_phys eIoni
is the step limiting process eIoni, yet the dE is 0, but the step length is completely unreasonable.
These are the worst kind of problems for a software developer. What happens if you change some of your em directives? What happens if you simplify your ElectricFieldSetup constructor? Only you can debug your progam.
