Hello everyone,

Im new in Openfoam and I want to analyze residence time distribution (RTD) following the tutorial 10 https://www.cfd.at/sites/default/fil...ExampleTen.pdf but for my own geometry (one inlet, one outlet).

I proceed as follow:
-running simpleFoam using the pitzDaily tutorial
-taking the U file from the last time_step and copying it into my 0 folder in the scalarTransportFoam folder
-running scalarTransportFoam and then foamToVTK

Everything runs without error. My problem is that the tutorial says to open the outlet file from the VTK folder (File > Open > VTK > outlet > outlet_..vtk > OK > Apply), but I dont find such a outlet.vtk file (see picture). I only find outlet.vtm when I go into boundaries in one of my timestep folders. Therefore I dont know how to proceed.

I know there are some similar post in this forum, but I couldnt extract from them something that can help me.

Can someone give me an orientation?. Thank you very much in advance

Hi troth,

Normally you should have outlet files in VTK format in the outlet directory created during "foamToVTK". Which operating system and openfoam version are you currently using? Just tried it out with version 6 and on ubuntu, it works as in the tutorial.

hello troth,
if you runned scalar without issue, you have solve already everything you need from OF side. you can use directly paraview with the .foam file without problems.
create .foam file -> touch RTD.foam
open it in paraview -> paraview RTD.foam (the current folder of the terminal should be the one of the .foam file)
then you can continue as a vtk file.... this was more problematic before, now you can use directly paraview.

best regards
