I am trying to refine a pipe surface (an annular cylinder). I am using surfaceToCell to make cellSet from the stl file of the pipe. But on running topoSet, I get following error:

--> FOAM FATAL ERROR:
Cannot read "/home/kishan/OpenFoam-Simulations/concentric-tube-heat-exchanger-new/constant/triSurface/pipeSurface.stl"

From function bool Foam::triSurface::read(const Foam::fileName&, const Foam::word&, bool)
in file triSurface/triSurface.C at line 304.

FOAM exiting

Here's my topoSet:

Not 100% sure, but I think it looks into constant/triSurface/ on its own. Have you tried providing only the file name without any path?

You need to specify it with $FOAM_CASE:

file  "$FOAM_CASE/constant/triSurface/pipeSurface.stl";
