Unable to run pipe tutorial

I have just installed v24.10 of TCAE-Lite. Initially I installed under Linux, sicne that is where I would really like to use the software. Having downloaded the pipe tutorial I load the case and get this message "Project configuration not fully valid according to TCAE-Lite 24.10 and may have been auto-corrected." When I try to run, I get a message that the caluclation cannot be started, and tha...

Total flow volume mismatch for inflow and outflow

This is more like an open question than a fully formed topic with both question and answer.


I am running an incompressible laminar flow simulation with the pimpleFoam solver. It has two openings on one side (n1 and n2) and one on the other (n3). I have set up the pressure boundary conditions so that the flow is driven primarily by the pressure applied at n3. The flow should be...

Error at parallel simulation

Hi, I'm a newbie to OpenFoam and I was trying to do the tutorials, I've been doing great but then I got to the motorbike one and tried to run in parallel the meshing and simulation but didn't work.

As you can see I set my meshing for parallel and gives me errors no matter if I use mpirun or mpiexec (I used both of them because I saw in other forums one of those should work), however if I...

Residual window

Hello CFDSupport Team,


I am experiancing a slight problem in Paraview during simulation. Window where residuals shall be seen is a bit strange. Is this some kind of a driver problem? Do you might give me any hint where to look?
