Hello,
I try to visualize results a Spectral Element Code. The mesh is
composed
of macros elements, each composed of n*n points. The ".dx" file is built
as
follow:
object 1 class array type float rank 1 shape 2 items 49 lsb binary
data file mesh2d.bin,0
#
# The regular connections
object 2 class gridconnections counts 7 7
#
object 3 class array type float rank 1 shape 2 items 49 lsb binary
data file uv.bin,0
attribute "dep" string "positions"
#
object "uv1" class field
component "positions" value 1
component "connections" value 2
component "data" value 3
#
object 4 class array type float rank 0 items 49 lsb binary
data file p.bin,0
attribute "dep" string "positions"
#
object "p1" class field
component "positions" value 1
component "connections" value 2
component "data" value 4
.......
.......
.......
object 1149 class array type float rank 1 shape 2 items 49 lsb binary
data file mesh2d.bin,112504
#
# The regular connections
object 1150 class gridconnections counts 7 7
#
object 1151 class array type float rank 1 shape 2 items 49 lsb binary
data file uv.bin,112504
attribute "dep" string "positions"
#
object "uv288" class field
component "positions" value 1149
component "connections" value 1150
component "data" value 1151
#
object 1152 class array type float rank 0 items 49 lsb binary
data file p.bin,56252
attribute "dep" string "positions"
#
object "p288" class field
component "positions" value 1149
component "connections" value 1150
component "data" value 1152
#
object "UV-Field" class multigrid
member "uv1" value "uv1"
member "uv2" value "uv2"
.....
.....
.....
member "uv287" value "uv287"
member "uv288" value "uv288"
#
object "P-Field" class multigrid
member "p1" value "p1"
member "p2" value "p2"
.....
.....
.....
object "ALL" class group
member "uv-velocity" value "UV-Field"
member "pressure" value "P-Field"
The problem arise when trying to plot Streamlines on this mesh. The
problem:
streamlines are troncated.
I check the same kind of dx network on a curvilinear mesh in one
part, and
there are no problems.
May be i didn't use the correct approach to define such grids.
Instead of
multigrid keyword i tried compositefield, but it that case, streamlines
are
computed only inside each macro elements, and there is no continuity of
these
streamlines.
thank you in advance for your help.
