sampleDict line errors
I wanna compare a 2D flow's velocity profiles at different locations, but when I run sample command, there somethings wrong:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create mesh for time = 0
--> FOAM FATAL IO ERROR:
keyword surfaces is undefined in dictionary "/Users/of/OpenFOAM/fpapcocp/system/sampleDict"
file: /Users/of/OpenFOAM/fpapcocp/system/sampleDict from line 20 to line 50.
From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 395.
the sampleDict is followed:
start (10 0 0);
end (10 0.5 0);
start (5 0 0);
end (5 0.5 0);
I don't know what's wrong,why there is information about surfaces? thank you very much!
Can you explain the problem you are solving and post checkMesh commands output?
It is not much clear from the data you have given.
Thanks for you reply. I am planning to simulate 2D flat plate boundary layer flow, so I need to choose two location to check the velocity profile. After some iterations, I use the command "simple" to gain the data in the lineX1 and lineX2.
btw,I also have no idea how to export the velocity vs t curve. would you or someone could give me some hints? Thanks you again.
Being short of time now, please refer following link for more detailed explanation.
Hope it helps.
Thank you CFDKid,
I did this in another way, just defined a surface which the lines are included.
so I missed define the surface, that's the reason. the new method you introduce i will try it.
