Dear Andy Bauer,
For the color map issue, I think ParaView 5.4.1 resolved it. But, I
could not figure out annotate time filter issue. may be it is just
simple problem but I am not sure. Coprocess routine is as follows and
python script is attached.
It would be appreciated if you make some advice.
void CoProcess(Foam::fvMesh& mesh, Foam::Time& runTime)
{
vtkNew<vtkCPDataDescription> dataDescription;
dataDescription->AddInput("input");
const double time = runTime.value();
const unsigned int timeStep = runTime.timeIndex();
dataDescription->SetTimeData(time, timeStep);
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)
{
// mesh moved? or mesh topology changed?
BuildVTKGrid(mesh, true);
}
UpdateVTKAttributes(mesh);
dataDescription->GetInputDescriptionByName("input")->
SetGrid(multiBlockDataSet);
Processor->CoProcess(dataDescription.GetPointer());
}
}
Regards.
