I am following the three week tutorial series for openfoam. I am a newbie to openFOAM and these forums so please be kind . I am running openFOAM8 on ubuntu 20.04. The tutorial I am following can be found here: https://www.cfd.at/downloads/FoamTut...leFourteen.pdf



Following the tutorial I get to page 7 where it askes me to run the following commands:

>blockMesh

>setFields

>sonicFoam



Instead of running sonicFoam I run rhoPimpleFoam as I am running openFOAM8


I get the following error:

file: /home/richard/shockTube/system/controlDict/functions/linesample/sets from line 65 to line 69.

    From function virtual Foam::ITstream& Foam::dictionaryEntry::stream() const
    in file db/dictionary/dictionaryEntry/dictionaryEntry.C at line 83.

Here is what my controlDict looks like:

From the debugger it looks like there is an error in the data dict, but from reading the documentation I am inputting the right variables.... I think.. the only missing from the tutorial is points according to the documentation:
https://www.openfoam.com/documentati...hp#x30-1331084

I think you want "sets (..) ;" instead of "sets {...}".
Any particular reason you took the openfoam.org version instead of the openfoam.com one?

[RichardKelly]

Thanks for that! Foiled by a bracket once again!.



Only reason I took the "openfoam.org" version is that is what installed when I installed using apt-get on Ubuntu. I did not compile myself.


Getting further along in the tutorials I am noticing I do not have cfmesh... wondering if that is a version thing or not.

[RichardKelly]

Install cfmesh after ...
