Hello, everyone!

I am a beginner of OpenFOAM, and I am struggling with it...
If possible, please give me a piece of advice!

Now I am trying to simulate sloshing behavior in a cylindrical tank.
Firstly, I tried to make a cylindrical mesh and fill the tank with water.
Then, I modified blockMeshDict and setFiledsDict in a sloshing tutorial
case as follows.

blockMeshDict
------------------------------------
convertToMeters 1;

vertices

(2 0 0) // 1
(0 2 0) // 2
(0 1 0) // 3
(1 0 4) // 4
(2 0 4) // 5
(0 2 4) // 6
(0 1 4) // 7
(-2 0 0) // 8
(-1 0 0) // 9
(-2 0 4) // 10
(-1 0 4) // 11
(0 -2 0) // 12
(0 -1 0) // 13
(0 -2 4) // 14
(0 -1 4) // 15
);

);

regions
(
boxToCell
{
box (-3 -3 -1) (3 3 2);
fieldValues
(
volScalarFieldValue alpha1 1
);
}
);
------------------------------------


Cylindrical mesh was generated correctly.
(I can it by using paraview.)
But, once I typed "setFileds", I received the
following error message. How do I work around?


------------------------------------
Reading setFieldsDict

Setting field default values
--> FOAM Warning :
From function void setFieldType(const fvMesh& mesh, const labelList& selectedCells,Istream& fieldValueStream)
in file setFields.C at line 101
Field alpha1 not found


wrong token type - expected word found on line 20 the label 0

file: ::defaultFieldValues at line 20.

From function operator>>(Istream&, word&)
in file primitives/strings/word/wordIO.C at line 77.

FOAM exiting
------------------------------------

I changed parameters in setFiledsDict in several ways,
but I failed to solve the problem. Maybe this arises from
a lack of understanding of OpenFOAM, it would give me
a great deal of pleasure if you give me some advice.
Thanks in advance!

Sincerely yours

Hi aki,

do you have a file "alpha1" in your "0" directory? I suppose, it's missing... but you can find examples in the tutorials folders...

Dear Martin

Thank you very much for prompt reply!
I made an unforced error...　You're right, "alpha1" was missing in "0" directory... I'm ashamed of myself.
Thank you very much for your advice!
