Write permissions giving --> FOAM FATAL ERROR:

[lhehjvgtycsd]

Hi,

After a lot of effort I now seem to have OpenFoam and Helyx installed on my system. For completeness in explaining my issue, I used the the method detailed in"Installation of the Latest 64 Bit Linux Binaries" at http://engys.github.io/HELYX-OS/installation/#v1606. However after following these instruction only Helyx was installed and not OpenFoam.

It appears that Helyx installed OpenFoam itself when I tried to mesh a test geometry - something like 'pulling OpenFoam' appeared in the Helyx output window and now it seems that OpenFoam is installed - see following output.

Ok, now to my issue. When I mesh my test geometry I get a problem with write permissions as shown in the following output. How do I solve this?

To me it looks like you are using the docker approach and the docker user does not have write permission in the folder where you want him to store the results.

I suggest for testing purposes to move your complete case folder somewhere out of you home structure and then do chmod -R a+rwX folder/where/case/movedto/ then try again.
