Hi everybody,

I'm a new user of OpenFoam on a MacBookPro. I've installed OpenFOAM v.1.5 with ParaView v.3.8.

Only two words to understand the case.

I'm trying to run the "sloshingTank3D6DoF" tutorial because I think is a very close case respect to that I have to develop. I have to model a rigid tank (Dimensions: 60x30x20 cm) partially filled by water subjected to a time history of acceleration. About that I've received the suggest to employ a:

"VOF free surface
flow solver with a moving mesh"

available in OpenFOAM.

Well, every time that I try to run "setFields" to set the liquid phase fraction to 1 I get back from the program this strings of error:


// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

Create mesh for time = 0

Reading setFieldsDict

wrong token type - expected word found on line 19 the label 0

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

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

but there's nothing wrong because I merely run the preset tutorial.

Am I wrong ?

Have you any suggest about that, but also about the simulation that I describe before ?

Every answer is appreciated

thanks to all,
cheers,

svevo

You might check your directories and version numbers. I had a similar problem crop up when I was switching between 1.7.1 and 1.6-ext versions of OpenFOAM. It looks to me like 1.7.1 creates the "0" subdirectory based on the "0.org", while 1.6-ext expects the "0" to be there already. Because of the different assumptions, the Allclean script is slightly different between the two versions.

[gsingle]

did you figure this out?

[nimasam]

the error says:
"Field gamma not found"
so look at directory 0, is there any gamma file there?
becareful
if there is gamma.org change into gamma
but if you use a higher version of openFoam, it
uses alpha1 instead of gamma so you should change in setFields gamma to alpha1

Hi, i have the same problem
I'm a new user of OpenFoam. I've installed OpenFOAM 3.0.0
would you please help me fix it?

Hi,

have you changed alpha.water.org to alpha.water? In the interFoam tutorial there is no alpha.water field present.
Just execute

cp ./0/alpha.water.org ./0/alpha.water

in the case directory.

Cheers

Hi, i have the same problem with setFields. I have changed the alpha.water.org in alpha.water. But the setFields is still not working und give the same warning. I really dont know how to slove it. Could anybody give me a hint? Thanks a lot!

did you solve the problem? i had the same one

You need to check the controlDict, the start time has to be set to 0. For my case that was the problem. If this doesn't work for you, you can copy your mesh in dam break case, run the setField from there and then take the alpha.water file or whatever you name it to your case folder.

[saatt]

When i do this(cp ./0/alpha.water.org ./0/alpha.water) and rewrite the words "alpha.water" in setFieldDict, the case can run again. But i don't know the reason.

> and rewrite the words "alpha.water" in setFieldDict

This is a ascii file, the cannot be any magic. Most probably you misspelled something.

Hey

I am new to openfoam. I am working with wigley hull case (https://github.com/OpenFOAM/OpenFOAM...oam/wigleyHull)

when I run setFields I get the following error

I have changed the name to alpha1 in 0 folder.

can anyome help me to solve it?
I would really appreciate it.

kind regards
