OpenFOAMv8 simulation error

alibaba25 · December 6, 2023, 20:20

hello everyone,
i am using openFOAM for the first time for an ongoing research. after compiling the solver in my case and opening paraview to visualize the simulation i run on this error when i press the play button in paraview :

error: in /home/ubuntu/openfoam/thirdparty-dev/paraview-5.6.0/vtk/io/geometry/vtkopenfoamreader.cxx, line 8295 vtkopenfoamreaderprivate (0x563bdbf13ce0): error reading line 20 of /home/''username''/''casename''/1.1/lagrangian/kinematiccloud/positions: expected punctuation token ')', found 0

any idea how to fix this ?

Hi,

this is probably due to the problem of OpenFoam switching to barycentric coordinates.

I don't know if they fixed this in the newer versions but what I usually do is convert the case to VTK using foamToVTK. You will then be able to read the lagrangian data.
