[mcstas-users] Opening multiple tables, SIGSEGV.

[Peter Kjær Willendrup]

Dear Alex,


What you are experiencing could (unfortunately) easily be a platform specific issue, it looks like you are on Windows?

Could you please send a copy of the instrument file and also any extra components, datafiles etc. to allow reproducing the issue?


Best,

Peter Willendrup

Hello everyone,
I am trying to simulate more “virtual” beamline in the same run. The setup is trivial, after my sample component there is a Au filter (Filter_gen component) and I want to detect the neutrons at different thickness of this.
I’ve two tables with the multiplier factor per energy that were used in two Filter_gen components:

COMPONENT filter_thin = Filter_gen(
    filename=thin,
    xwidth=0.045,
    yheight=0.045)
WHEN (foil==1) AT (-0.158,-0.048,0.46) RELATIVE Armsample
GROUP Foils

COMPONENT filter_thick = Filter_gen(
    filename=thick,
    xwidth=0.045,
    yheight=0.045)
WHEN (foil==2) AT (-0.158,-0.048,0.46) RELATIVE Armsample
GROUP Foils

I can run the simulation only when there is one filter component (commenting the other), otherwise:

This tables are only 300 lines and I have more than 10GB of free ram, so where I have to look at to find the problems? I thought  the overlapping was an issue but after inserting the GROUP command nothing change.

Thank you for your help

Alex
