Hallo
are you able to recommend a free software, like paraview or VisIt, to visualize three dimensional water flow resulting from a basement simulation?
Which data formats do i have to use? Are there any experiences, hints or maybe tutorials?
Thanks for your answers.

hi beroubt,
for advanced visualization we recommend paraview.
to generate a visualization of 3d topography including the water surface elevation (colored with water depth) you need at least the following two special_output blocks in basement:
SPECIAL_OUTPUT {
type = element_centered
format = vtk
output_time_step = 1
values = (depth wse)
}
SPECIAL_OUTPUT {
type = node_centered
format = vtk
output_time_step = 1
values = (z_node deltaz)
}
then you can import all files into paraview and apply the needed filters (see example state file here, just update the path to your result files).
cheers, sam

Hi sam,
using
SPECIAL_OUTPUT {
type = node_centered
format = vtk
output_time_step = 1
values = (z_node deltaz)
}
i've got Block-Error: Output of type 'deltaz' defined in 'values' can not be generated without bedload computation.
Do you have a (simple) work around?
thanks beroubt

ok, this example was including an erodible bed to visualize the changing topography as well.
just skip the 'deltaz' in 'values' and your pure hydraulic simulation will run.
eventually you need some small adaptions in the provided paraview state file...
