Geometry rescaling error of Amrvis slices #4
Description
I encountered the following error running the AMReX tutorial HeatEquation_EX1_C and using Amrvis to visualize the results. The error occurs in both DIM = 2 and 3 dimensions, but I will cite the DIM = 3 case here.
Plot files were produced using
./main3d.gnu.ex inputs_3d
One plot file was brought into amrvis
amrvis3d plt00000 &
Invoking the menu item Help --> Info... yields the following file information:
plt00000
HyperCLaw-V1.1
time: 0
levels: 1
prob domain:
level 0: ((0,0,0) (127,127,127) (0,0,0))
refratios:
probsize: 2 2 2
prob lo: -1 -1 -1
prob hi: 1 1 1
Note that the physical problem domain is [-1, 1] x [-1, 1] x [-1, 1].
To look at a two dimensional slice of this data, I ran the batch command,
amrvis3d -newplt -zslice 80 plt00000
and brought this slice into amrvis via
amrvis3d -fab plt00000.phi.zslice.80.Level_0.fab
The information on this file reads
plt00000.phi.zslice.80.Level_0.fab
FromFAB
time: 0
levels: 1
prob domain:
level 0: ((0,0,80) (127,127,80) (0,0,0))
refratios:
probsize: 1 1 1
prob lo: 0 0 0
prob hi: 1 1 1
The domain has been erroneously rescaled to [0, 1] x [0, 1] x [0, 1].
My original intent was to bring this Fab slice into amrvis2d so that I may extract line plots (which doesn't seem to be possible within amrvis3d). The command
amrvis3d -fab plt00000.phi.zslice.80.Level_0.fab
happily worked, but with the same rescaling error as above.
Previously I had encountered the same rescaling problems using amrvis2d to batch produce slices, which in that case were data along a line.
