I have an openfoam 9 installed on my computer, and I successfully ran blockMesh of geometry created in openFoam 2 on my openFoam-9. When I tried to run paraFoam, I got an error shown below. I am thinking different version of openFoam may be causing the error, and I cant install openfoam 2 on my machine due to incompatibility with my machine. I will like to check if anyone has suggestion on what to do to fix the error.

Thanks.

Hi Olabode,

The issue does not seem to occur because of 2 versions of FOAM. Instead as we can clearly follow, the error lies here

--> FOAM FATAL IO ERROR:
Essential entry 'value' missing

specifically at line 31 to line 34 of 0/T/boundaryField.

Maybe you already have fixedValue type BC like this in 0/T for ceiling

ceiling
{
type fixedValue;
value XXX;
}

But either the XXX is missing or a semi colon in both of the above lines.

P.S. Maybe if you post your T file then it will be much easier to find the cause.


Regards,
Shubham

Thank you very much Shubham, for the 0/T file, its shown below

try modifying

Thank you very much Shubham, I believe it get better with different error

The current ceiling line looks like this


internalField uniform 300;

boundaryField
{
floor
{
type zeroGradient;
}

ceiling
{
type groovyBC;
variables "v=1;b=0.0001;P=150;n=0.2;s=pos().x-v*time();zi=pos().z;maxZ=max(pts().z);maxX=max(pts ().x);maxY=max(pts().y);yi=pos().y;";

fractionExpression "0";
value uniform 0;

[Bodman06]

I believe the new error is coming 0/U

ceiling
{
type marangoni;
marangonicoeff 0.1; //(dsigma/dt)*1/mu
//value uniform (0 0 0);
}

[SHUBHAM9595]

Yes, you need to uncomment the

ceiling
{
type marangoni;
marangonicoeff 0.1; //(dsigma/dt)*1/mu
//value uniform (0 0 0);
}

to

ceiling
{
type marangoni;
marangonicoeff 0.1; //(dsigma/dt)*1/mu
value uniform (0 0 0);
}

[Bodman06]

It works fine now, thank you very much Shubham, I uncomment the ceiling

//value uniform (0 0 0);

I could see the mesh

[Bodman06]

I was able to generate the mesh, using Allrun file as shown below
#!/bin/sh
cd ${0%/*} || exit 1 # Run from this directory

# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions

application=`getApplication`

runApplication blockMesh
#cp 0/alpha.solid.orig 0/alpha.solid
runApplication topoSet -dict system/topoSetDict1
runApplication refineMesh -overwrite -dict system/refineMeshDict1
#rm log.topoSet
#rm log.refineMesh
#runApplication topoSet -dict system/topoSetDict2
#runApplication refineMesh -overwrite -dict system/refineMeshDict2
#runApplication setFields
runApplication decomposePar
runParallel `getApplication`


However, I will like to generate meltpool with laser moving across the bed. I have other files which may be useful in achieving that, just that they have to be arranged well and included in the Allrun file. I believe those other files can be in the system folder. I attached them with this message.

[SHUBHAM9595]

Hi Olabode,

Unfortunately, I'm not able to understand what exactly u want to do....Can u please elaborate little bit....and maybe its better if you can put tthat in a new thread....as this new question might not go hand in hand with this thread title......this will also enable other much experienced folks than me to help u....

[Bodman06]

I was getting this error message when I open up my solution in paraview. although I am still try to understand the error from the files which I attached

[SHUBHAM9595]

Not sure but might be related to the incorrect installation of paraview.

Anyways, as it seems a WARNING instead of ERROR......u should still be able to analyze all the fields in the paraview...

[Bodman06]

Thank you Shubham, I attempted running blockmesh, but I was getting this error, Although I the folder in set it was locked.
