Ok, so you are correctly using everything. The question is now on the *OpenFOAMReader and if it properly use MPI to read and distribute the data.* *Which unfortunately I don't know.*
*If you want to force a redistribution of your data across your nodes, you can use the D3 filter just after your reader.* *Seb* On Thu, Jun 5, 2014 at 11:44 AM, Daniele Obiso < [email protected]> wrote: > Hi Sebastien, > > here you can find the main parts of the script. > > > > -------------------------------------------------------------------------------------------------------------------------------- > *try: paraview.simple* > *except: from paraview.simple import ** > *paraview.simple._DisableFirstRenderCameraReset()* > > *RenderView1 = CreateRenderView()* > > *##### Lights* > * options * > *##### Screen** options* > > *##### Set scale parameters* > *a1_Cp_PVLookupTable = GetLookupTableForArray( "Cp", 3, RGBPoints=[-1, > 0.0, 0.0, 1.0, 0.75, 1.0, 0.0, 0.0], VectorMode='Magnitude', > NanColor=[0.498039, 0.498039, 0.498039], NumberOfTableValues=100, > ColorSpace='HSV', LockScalarRange=1 )* > *a1_Cp_PiecewiseFunction = CreatePiecewiseFunction()* > *ScalarBarWidgetRepresentation1 = CreateScalarBar(Position=[0.33, 0.95], > Title='Cp [-]', Orientation = 'Horizontal', Position2=[0.4, 0.04], > Enabled=1, LabelFontSize=12, LabelColor=[0.0, 0.0, 0.0], > LookupTable=a1_Cp_PVLookupTable, TitleFontSize=12, TitleColor=[0.0, 0.0, > 0.0] )* > > *##### Legend position* > *GetRenderView().Representations.append(ScalarBarWidgetRepresentation1)* > > *##### Time* > *RenderView1 = GetRenderView()* > *AnimationScene1 = GetAnimationScene()* > *AnimationScene1.EndTime = 2500* > *AnimationScene1.AnimationTime = 2500* > *RenderView1.ViewTime = 2500* > > *##### Open the model: volume mesh* > *foam_foam = OpenFOAMReader( FileName='../case.foam' )* > *foam_foam.CellArrays = ['Cp']* > *foam_foam.CaseType = 'Reconstructed Case'* > *foam_foam.MeshRegions = ['internalMesh']* > > *DataRepresentation2 = Show()* > *DataRepresentation2.ScalarOpacityUnitDistance = 0.01* > *DataRepresentation2.Representation = 'Outline'* > *DataRepresentation2.EdgeColor = [0.0, 0.0, 0.5]* > *DataRepresentation2.Visibility = 0* > > *##### Slice* > > *RenderView1.CameraViewUp = [0.0, 1.0, 0.0]* > *RenderView1.CameraPosition = [1.5, 0.3, 18]* > *RenderView1.CameraFocalPoint = [**1.5, 0.3, 1]* > *RenderView1.CameraClippingRange = [18, 18]* > *RenderView1.CameraParallelScale = 0.9* > > *SetActiveSource(foam_foam)* > > *Slice1 = Slice( SliceType="Plane" )* > *Slice1.SliceOffsetValues = [0.0]* > *Slice1.SliceType.Origin = [0, 0, 0]* > *Slice1.SliceType.Normal = [0, 0, 1]* > *Slice1.SliceType = "Plane"* > *DataRepresentation3 = Show()* > *DataRepresentation3.Visibility = 1* > *DataRepresentation3.EdgeColor = [0.0, 0.0, 0.5]* > *DataRepresentation3.ColorArrayName = 'Cp'* > *DataRepresentation3.LookupTable = a1_Cp_PVLookupTable* > > *##### Animation Time* > *RenderView1 = GetRenderView()* > *AnimationScene1 = GetAnimationScene()* > *AnimationScene1.EndTime = 2500* > *AnimationScene1.AnimationTime = 2500* > *RenderView1.ViewTime = 2500* > *AnimationScene1.PlayMode = 'Sequence'* > *AnimationScene1.NumberOfFrames =10* > > *KeyFrameAnimationCue3 = GetAnimationTrack( 'Origin', 2, > proxy=Slice1.SliceType)* > *KeyFrame1111 = CompositeKeyFrame( KeyValues=[0] )* > *KeyFrame2222 = CompositeKeyFrame( KeyTime=1.0, KeyValues=[1.4] )* > *TimeAnimationCue1 = GetTimeTrack()* > *TimeAnimationCue1.UseAnimationTime = 0* > *KeyFrame3333 = CompositeKeyFrame( KeyTime=1.0, KeyValues=[2500] )* > *KeyFrame4444 = CompositeKeyFrame( KeyValues=[2500] )* > *KeyFrameAnimationCue3.KeyFrames = [ KeyFrame1111, KeyFrame2222 ] * > *TimeAnimationCue1.KeyFrames = [ KeyFrame3333, KeyFrame4444 ]* > > > *##### Write* > > *WriteAnimation('Cp.png', Magnification=1, Quality=2, FrameRate=1.000000)* > > *##### End* > *Render()* > > > -------------------------------------------------------------------------------------------------------------------------------- > > Hope this can help you to understand the problem! > > Thanks for the availability! > Daniele > > > > > > > > > > > > > On 06/05/2014 07:04 PM, Sebastien Jourdain wrote: > > Is it using the VTK classes or the paraview Proxy? > > Moreover, the reader/source is responsible to distribute the data to > properly handle parallelism. > If it does not, then you right, everything will happen on the root node. > > Hense a quick look at the script can help us determine which part need > to change in order to truly use parallel processing. > > Seb > > > On Thu, Jun 5, 2014 at 8:32 AM, Daniele Obiso < > [email protected]> wrote: > >> Hi Sebastien, >> >> thanks for the reply! >> >> The script is about creating slice and sweep animation.
