.vti file could not be opened

Hi everyone;

I am a beginner in Palabos and I am trying to run the cavity2D example on windows. After loads of works, finally I could generate the .exe file which could be run properly. But at the end of the simulation, this error has appeared:

Saving VTK file …
could not open file ./tmp/vtk012800.vti
Assetation failed: ostr && (bool)(*ostr), file D:\palabos\src\io\serializerIO.cpp, line 93

unfortunately, I can not obtain any visualized results from the simulation. It should be also noted that there is not any vti file in tmp folder.

Has anyone experienced the same issue?
I will appreciate your help!

I have the same issue only with the permeability example. How did you solve it?

Thank you
