multiphaseEulerFoam FOAM FATAL IO ERROR

qutadah.r · December 7, 2021, 07:25

Hi everyone, I am having the following error when running a two-phase 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/EE2F-MUSIG/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.

Any help would be appreciated! Thanks!

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
Please can anyone help!

Try changing nOuterCorrectors nNonOrthonormalCorrectors.

You can also try changing schemes.

I have tried to increase and decrease the value of the nOuterCorrectors nNonOrthogonalCorrectors, I have also tried to change several values in the fvscheme file but nothing is working.

I also tried to calculate using the 2D version of the same hydrofoil and the calculation started running but after a while, it terminated with an error message as shown below.

Please I need your help with this problem

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

I have uploaded the zero and system folders in zipped format, kindly find attached

night-hawk · December 9, 2021, 22:13

I will check. I will let you know if I am able to made any progress.

Ok, Thank you

Night-hawk 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.

qutadah.r Senior Member qutadah Join Date: Jun 2021 Location: USA Posts: 101 Rep Power: 4	Hi everyone, I am having the following error when running a two-phase 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/EE2F-MUSIG/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. Any help would be appreciated! Thanks!

qutadah.r Senior Member qutadah Join Date: Jun 2021 Location: USA Posts: 101 Rep Power: 4	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
