Hi everyone, I am having the following error when running a twophase flow in OpenFOAM.
The original case works perfectly and doesnt have any issues, I come across this issue when i change some values of alpha or U in the boundary conditions... * I am using collated filehandler and parallel processing using two nodes, 48 processors each. Code:
> FOAM FATAL IO ERROR: Expected a ')' while reading binaryBlock, found on line 21 the word 'e▒L▒3' file: /rwthfs/rz/cluster/hpcwork/jg235250/SetupsMarkus/EE2FMUSIG/06_3D_Pumpe_M1_v6_Qtot696_IGVF_5_SST_OF9_EE2F_MUSIG/0.288173000000247/U.water at line 21. From function Foam::Istream &Foam::Istream::readEnd(const char *) in file db/IOstreams/IOstreams/Istream.C at line 109.

so i dont know what caused this still, i was using nano editor to edit the binary boundary files... I just copied the original case again and used vi editor and it worked.... Even though i did the same and edited the binary files with nano and got this error .....
If someone knows if nano editor messes up the binary files somehow please let me kindly know, thanks

I am experiencing almost similar issues, in my case I swapped out the cavitating bullet geometry with a 3D hydrofoil and I tried to carefully change the boundary conditions. The mesh was ok but when I ran the command "interPhaseChangeFoam" I got the error below

You can also try changing schemes.

There is probably issue with boundary condition. Can you upload your case folder.

Nighthawk I removed the polymesh folder just like you suggested and the file size dropped significantly. I have uploaded the 3D case folder.
Secondly, as you can see from the screenshot attached, the 2D case is currently calculating thanks to your correction but so far I have not seen a single calculation folder been generated by OpenFOAM in my case folder. It seems abnormal. Please what can I do about this?

Your write interval seems don't match with deltaT.
