Hi Seongmo,
I am using following steps to add annotation to Catalyst,
1 - Create a ProgrammableFilter
2 - Add following code to it (don’t forget to modify epoc)
import paraview.simple
import paraview.servermanager
import datetime
import locale
# get output port and copy it to input
out = self.GetOutput()
out.ShallowCopy(self.GetInput())
# define epoc
locale.setlocale(locale.LC_TIME, "en_US")
epoc = datetime.datetime(1949, 12, 1, 0, 0, 0)
# get time value
tval = self.GetInput().GetInformation().Get(out.DATA_TIME_STEP())
# find time by adding hours
#t1 = epoc+datetime.timedelta(seconds=tval)
t1 = epoc+datetime.timedelta(hours=tval)
tstr = t1.strftime(“%d-%b-%Y %H:%M:%S UTC")
# output
label = vtk.vtkStringArray()
label.SetNumberOfComponents(1)
label.Resize(1)
label.SetName("TimeLabel")
label.SetValue(0, t1)
out.GetFieldData().AddArray(label)
3 - Add AnnotateGlobalData1 and select “TimeLabel” as array (needs
MergeBlocks filter in case of multiblock datasets)
You could modify the section related with generation of time string for
your needs. I hope it helps.
Regards,

Hi Seongmo,
Please keep the conversations on the mailing list so that anyone can
follow along or participate. Also, these types of things often get
lost in my inbox when they don't make it back to the ParaView mailing
list.
What version of ParaView Catalyst are you using? I think the annotate
time filter should work with Catalyst but I haven't verified that. I
vaguely remember others using that filter with Catalyst though. Also,
I think the colormap bug was fixed. If you have a way of sharing a
sample that demonstrates either of those bugs I can try taking a look
at the issue.
Best,
Andy

Dear Andy Bauer
I have a quick question.
Is it possible to have annotate time filter processed in catalyst
adaptor? Current my code cannot that filter.
BTW, image extracted from catalyst looks different from render
view of paraview at the time of writing a script. e.g., pressure
colormap legend is missing.
Regards
Seongmo

Hi,
My guess is that the TimeStep isn't getting set properly in the
adaptor (though it looks like it should be in
"dataDescription->SetTimeData(runTime.value(),
runTime.deltaTValue());"). My suggestion would be to add in the
following to either the RequestDataDescription() or
DoCoProcessing() methods in the python script to see what
Catalyst thinks the time step is:
print("In script2.py, the data time step is ",
datadescription.GetTimeStep())

Hi,
I wrote a OpenFOAM adaptor for Catalyst.
In the ParaView, the connection is made good and shows
filtered flow field as written in the python script.
However, filename_%t and image_%t is not expanded as time
marching but just write filename_0 and image_0.png.
As far as I know, %t should be replaced with current time as
given in dataDescription->SetTimeData.
Any help would be appreciated.
FYI, python script is attached and snippet of my OpenFOAM
Adaptor code for Catalyst is as follows:
// icoFoam.C
#ifdef USE_CATALYST
Foam::HashTable<string> options = args.options();
IStringStream is(options["scriptList"]);
wordList scriptList = readList<word>(is);
OFAdaptor::Initialize(scriptList, mesh);
#endif
while (runTime.loop())
{
runTime.write();
#ifdef USE_CATALYST
OFAdaptor::CoProcess(mesh, runTime);
#endif
}
#ifdef USE_CATALYST
OFAdaptor::Finalize();
#endif
// OFAdaptor.C
void CoProcess(Foam::fvMesh& mesh, Foam::Time& runTime)
{
vtkNew<vtkCPDataDescription> dataDescription;
dataDescription->AddInput("input");
dataDescription->SetTimeData(runTime.value(),
runTime.deltaTValue());
if (runTime.end())
{
// assume that we want to all the pipelines to execute
// if it is the last time step
dataDescription->ForceOutputOn();
}
if
(Processor->RequestDataDescription(dataDescription.GetPointer())
!= 0)
{
Foam::polyMesh::readUpdateState meshState = mesh.readUpdate();
if(meshState != Foam::polyMesh::UNCHANGED)
{
BuildVTKGrid(mesh);
}
UpdateVTKAttributes(mesh);
dataDescription->GetInputDescriptionByName("input")->SetGrid(multiBlockDataSet);
Processor->CoProcess(dataDescription.GetPointer());
}
}
