Hello,

I am a new user of Open Foam

I am mapping the data from an old file to a new mesh file using the following command:

# mapFields /FolderName -consistent -noFunctionObjects -mapMethod cellVolumeWeight -fields '(U,P)'

Terminal throws no fatal error or any other error.

next I hit paraFoam to visualize the mapped U and P fields, however I don't see any scalar/vector field in paraView.

Can anyone tell me what am i missing here?

Quick answers:
  1. It would be easier to diagnose the problem if you had followed the instructions given here: http://www.cfd-online.com/Forums/ope...-get-help.html
  2. Information that is missing:
    1. What is the complete output text given by mapFields?
    2. What do you see in ParaView?
Please keep in mind that we cannot see what you're seeing, if you don't show it to us.

Hi


I think I know what the problem is, but I did not find a solution yet.



I also have a large case (I need very small cells for calculation), and I would like to map the results to a coarser mesh for visualisation. I was hoping to do so with mapFields, but it only maps the latestTime:


Create databases as time

Source time: 2
Target time: 2
Create meshes

Source mesh size: 45000 Target mesh size: 450


Consistently creating and mapping fields for time 2



As a result, I only see the mapped results in paraview for the last time.


Is there an option to mapFields for all timesteps? I know about the option -sourceTime, but it only takes scallars of latestTime, not 'all' or something likely.


Best regards
Arne
