problems with particle ostream and ILList

stephan · April 17, 2009, 05:27

Hi all,

i have a strange problem running my own lagrangian solver in parallel.
once particles moves from one processor to the other foam complains like this:
[0] Expected a ')' or a '}' while reading ILList<LListBase, T>, found on line 0 an error
[0]
[0] file: IOstream at line 0.
[0]
[0] From function Istream::readEndList(const char*)
[0] in file db/IOstreams/IOstreams/Istream.C at line 159.
so it seems that something is wrong with the stream but i have no clue what exactly went wrong and why.
Writing data /reading data and restarting runs works fine so i guess i something to do with the routine
Foam::Ostream& Foam:

perator<<(Ostream& os, const parcel& p).
(which is declared friend to the parcel class and still a member of the parcel class (what is strange for me too))
I hope somebody might help me.
Any help would be really appreciated.

Thanks in advance!
Regards
Stephan

Implement binary IO as well. Look at e.g. solidParticle.

Hi Mattijs,

thanks for the hint - i used dieselFoam as the base version but still having the mentioned problems. actually i can write/read/restart in binary formats too and as shown in dieselFoam i implemented binary io too - but still it failes.
does anybody has an idea how to efficiently debug this problem.
still thanks to mattijs
regards

Hi, stephan
I have an exactly the same problem. How did you fix yours?
Waiting to be enlightened .

I fixed my bug it turns out that after I introduced new private member to my particle class I forgot to put them also in the Ostream operator<<. I left it here hopefully it will help anyone who has the same problem.

Thanks Edison_Ge!

I made the exact same mistake! I would have stuggled all day if I didn't catch your post.
