Hello everyone,
I have a question about cfx5-post. This question is almost the same like Roy Chen had in 2002: http://www.cfd-online.com/Forum/cfx_....cgi/read/3538 As he I also want to know an average value across a plane. But I want to move this plane and plott all the average values along the movementline. In my case I need the distribution of the mass averaged temperature. Does anyone know who to achieve this without having a lot of planes and also as many expressions. There needs to be an easier way than having thousand planes. Probably with power syntax? Thanks for your help, Aloise |

Record a session file that does this for one plane, then go and edit the session file so that you put a "for" loop around the plane generation and temperature calculation. There an example in the CFX-Post doc under Power Syntax that is fairly similar. Miike

Thanks Mike!!
It toke me a while to figure out how to get this working. For others facing the same problem here is me result: VIEWPORT MANAGER: Viewport List = Viewport Order = 1, 2, 3, 4 Maximized Viewport = -1 END VIEWPORT MANAGER: Viewport List = Viewport Order = 1, 2, 3, 4 Maximized Viewport = -1 END VIEWPORT MANAGER: Viewport List = Viewport Order = 1, 2, 3, 4 Maximized Viewport = -1 END ! #Variablen hier verändern ! open(Filehandle,">>C:\Temp\kellerlog.log"); ! $length = 320; ! $steps = 320; ! $delimiter = ","; ! $i = 0; ! $einheit = "mm"; ! while($i<=$steps){ PLANE:Plane 1 Apply Instancing Transform = On Apply Texture = Off Blend Texture = On Bound Radius = 0.5 [m] Colour = 0.75, 0.75, 0.75 Colour Map = Rainbow Colour Mode = Constant Colour Scale = Linear Colour Variable = Pressure Colour Variable Boundary Values = Hybrid Culling Mode = No Culling Direction 1 Bound = 1 [m] Direction 1 Orientation = 0 [degree] Direction 1 Points = 10 Direction 2 Bound = 1 [m] Direction 2 Points = 10 Domain List = All Domains Draw Faces = On Draw Lines = Off Instancing Transform = Default Transform Invert Plane Bound = Off Lighting = On Line Colour = 0, 0, 0 Line Colour Mode = Default Line Width = 1 Max = 0.0 [Pa] Min = 0.0 [Pa] Normal = 1 , 0 , 0 Option = YZ Plane Plane Bound = None Plane Type = Slice Point = 0 [m], 0 [m], 0 [m] Point 1 = 0 [m], 0 [m], 0 [m] Point 2 = 1 [m], 0 [m], 0 [m] Point 3 = 0 [m], 1 [m], 0 [m] Range = Global Render Edge Angle = 0 [degree] Specular Lighting = On Surface Drawing = Smooth Shading Texture Angle = 0 Texture Direction = 0 , 1 , 0 Texture File = Texture Material = Metal Texture Position = 0 , 0 Texture Scale = 1 Texture Type = Predefined Tile Texture = Off Transform Texture = Off Transparency = 0.0 Visibility = On X = $i [$einheit] Y = 0.0 [m] Z = 0.0 [m] OBJECT VIEW TRANSFORM: Apply Reflection = Off Apply Rotation = Off Apply Scale = Off Apply Translation = Off Principal Axis = Z Reflection Plane Option = XY Plane Rotation Angle = 0.0 [degree] Rotation Axis From = 0 [m], 0 [m], 0 [m] Rotation Axis To = 0 [m], 0 [m], 0 [m] Rotation Axis Type = Principal Axis Scale Vector = 1 , 1 , 1 Translation Vector = 0 [m], 0 [m], 0 [m] X = 0.0 [m] Y = 0.0 [m] Z = 0.0 [m] END END VIEWPORT MANAGER: Viewport List = Viewport Order = 1, 2, 3, 4 Maximized Viewport = -1 END LIBRARY: CEL: EXPRESSIONS: Tbulk=massFlowAve(Temperature )@Plane 1 END END END EXPRESSION EVALUATOR: Evaluated Expression = Tbulk END > forceupdate EXPRESSION EVALUATOR !

Hello,
now that i know how to get these average values across a plane i would like to get them plotted in a chart. The file I get can`t be reread from cfx as file-import to create a chart-line. Can anybody tell me what I need to consider? Or is there even an easier way to get these average values plotted in a chart? Thanks for your help, aloise |
