foam2columns's Introduction

foam2Columns

Usage

It supports any number of fields and transforms them to this format:

L1: x y z var1 var2 var3_x var3_y var3_z ...
L2: x y z var1 var2 var3_x var3_y var3_z ...
.
.
.
Ln: x y z var1 var2 var3_x var3_y var3_z ...

where n is the cell number, and var1(p), var2(T) var3(U)are the input variables:

foam2Columns -fields "(p T)"

Yes, it supports volVectorField:

foam2Columns -vectorFields "(U)"

Or together:

foam2Columns -fields "(p T)" -vectorFields "(U)"

Thanks for ZmengXu. With his help, it supports lagrangian fields:

foam2Columns -lagrangianFields "(d T)"

Or together:

foam2Columns -fields "(p T)" -vectorFields "(U)" -lagrangianFields "(d T)"

The results are save in $FOAM_CASE/postProcessing/foam2Columns/$time/Eulerian_*, and $FOAM_CASE/postProcessing/foam2Columns/$time/Lagrangian_* for lagrangian fields.

foam2columns's Issues

when you only want to get a vector field (e.g., U)

Nice jobs! One suggestion of mine is to change

forAll (allScalarFields[0], cellI)

to

forAll (mesh.C(), cellI)

to get rid of the error when you only want to get a vector field (e.g., U) with the following command:

foam2Columns -vectorFields "(U)" -latestTime

OFstream endl is much slower than nl

The previous foam2Columns write slowly when the cell number is big.
I found that it is because of the endlissue, it is far away slower thannl when we want to create a new line.`

How to compile?

Hi, I am new to OpenFOAM. Could you tell us the instructions for compilation?

moving `label iParticle(0);` outside of the loop.

@ZSHtju suggested moving Line 195 label iParticle(0); to outside of the loop Line 195.
