Hello everyone!


I'm running DPMFoam for simulating a flow with lagrangian particles injection. It solves ok, but when I try to represent lagrangian particles in Paraview, the following error pops up: "Error reading line [...] /lagrangian/kinematicCloud/positions: Expected punctuation token ')', found 0". When I open the referenced file, it looks like this:

FoamFile
{
    version     2.0;
    format      ascii;
    class       Cloud<basicKinematicCollidingParcel>;
    location    "0.16/lagrangian/kinematicCloud";
    object      positions;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

...

Is this format ok? or compatible with Paraview? It looks to me like Paraview is trying to read three coordinates because it complains that after the third number there's no a ')', but there are actually four numbers between parenthesis.


I'm using OF v6, and paraview 5.4.0


I've tried both opening the .foam file and exporting to VTK, but similar errors show up.



Thank you!




I just found the answer here: Unable to read Positions file in IcoUncoupledParcelFoam in Paraview

...same problem with me on Ubuntu 19.10, OF6
is it due to Writing the old 'positions' file in Lagrangian solvers as of OpenFOAM 5.x ?

same problem with OF7 and ParaView 5.10
