[OpenFOAM] Alternative to paraFoam

ericnutsch · May 25, 2010, 02:00

I have had moderate success getting paraFoam to work in the past, so I put together a stupid simple bit of code that does the same thing, just reliably!

Step1: Unzip the attached file and put it into your case directory
Step2: Type ./ParaDisplay into the terminal and hit enter
(while in the case directory of course; operates just like Allrun)

All it does is automate the process of using foamToVTK, opening paraview, locating the vtk file and opening it. But 2 minutes here and there add up.

Let me know what you think.

Hi Eric!
Well, it works, so why not:-) I like it, thanks for sharing!
best,
Michael

Thanks, Eric.
I was having a bit of trouble and I'm unsure of how to solve it.

The line:
paraview --data=VTK/${PWD##*/}_..vtk

raises the error
File ' "VTK/cavity_..vtk" ' cannot be read.

I'm guessing it is a trivial fix, but I'm still a bit lost.
Any help would be greatly appreciated.

Thanks.

Hi skarnani,

Try doing the process manually by first running foamToVTK in the shell.

You can then go into paraview and see if the files are in yourCase/VTK and open them up. If both those things work, but the code doesnt, post back with an ls of your case file and I will see if I over looked something.

Note that there is an issue using this script with OpenFOAM1.5Dev, since sourcing the openfoam variables conflict with paraview. (Still pondering a good approach to this)

Or if you're using PV 3.8 (downloaded from either Kitware or openfoam.com is ok), try its builtin reader by
touch ${PWD##*/}.foam && paraview --data=${PWD##*/}.foam
under your case directory.

Thank you Eric and Takuya for the replies.
By manually running foamToVTK, I can open paraview and then open the results files. However, I think you called it right, as I am using OpenFOAM-1.5-dev.

Thanks for the help though.

Yeah for the time being, you can open a new shell that is not sourced, cd to the working directory and run ParaDisplay from there.

The extra shell reduces the convenience, but it can be handy in some situations.

I use 1.5Dev myself and will post an updated version of ParaDisplay once I get it working.
