Hi

I'm having problems using star4ToFoam tool to import .cel and .vrt file to OpenFOAM format. Please see below terminal output. Anybody have any ideas on how to solve this?

Best regards Kasper Skriver

Strangely enough this appears have been patched about 1/2-year ago. There might indeed be a reason to use the OpenFOAM-1.5.x bugfix repository, or is that patched version not working for you either?

meshTables: bugfix and cleanup

- fixed segfault due to missing ++ in namesList()
- use more of the new dictionary functionality

Hi Mark,

thanks for answering and helping out. I am not familiar with the bugfix repository. How do I use this info you give me?

I am finding this page http://www.opencfd.co.uk/openfoam/download.html but can't get access to git://

I suppose that I should execute this: git clone git://repo.or.cz/OpenFOAM-1.5.x.git in a terminal and locate the commit specified. But what then?

1. clone from the repo.or.cz location (I believe http transport works too). This gets you the latest version with all of the bugfixes. This is what you should be using.

2. I would recommend making your own local branch (eg, 'kasper') based on the remote repository (origin/master). This lets you make local modifications, but still benefit from the bugfixes.

3. Remake as usual (Allwmake) and go grab lunch.

Later on, you can do a periodic 'git fetch' to update your tracked version of the repo.or.cz repository and use 'git merge' and recompile via Allwmake at your own leisure.


BTW: the learning curve with git is a bit steep (more especially if you haven't used an scm before), but there are a few git video tutorials kicking about that help. The Randal Schwartz google tech talk is really good for a bit of information of what is going on behind the scenes. The time invested there will help.
