Hi,

I ran a case with two solid regions, If at the end of the simulation I run

chtMultiRegionSimpleFoam -postProcess -func wallHeatFlux -region solid1

I got this error

Build  : dev-540796ea3aaf

Create time

Create solid mesh for region solid1 for time = 0

Create solid mesh for region solid2 for time = 0



--> FOAM FATAL ERROR: 
No fluid meshes present

    From function chtMultiRegionSimpleFoam
    in file ../createMeshesPostProcess.H at line 5.

FOAM exiting

To reproduce the error just run the ./run bash

Is this a bug I should report?
Thanks

Use this utility I compiled through 4.x, dev, and plus version I hope this will work with 5.x too just in make/option chane $(WM_PROJECT_USER_DIR)/src to $(LIB_SRC) and compile.

Hi thank you for support, but I think I can't use your files so easily
You changed all options by defining new thermoModels as MythermoModels e.g.

Greetings to all!

@student666: I've tested this and it was in fact a bug or at least a missing feature. I've submitted a patch for it here: https://bugs.openfoam.org/view.php?id=2684

Which installation instructions have you followed?

Best regards,
Bruno

Hi Bruno,

my actual installation is as by the following thread
Problem for OF-dev on linuxMint 18.2 Sonya

so the link is:

https://openfoam.org/download/dev-ubuntu/

You can change it to $(LIB_SRC)/thermophysicalModel/what ever u want
Or there is old.option file rename it as option it will work

Quick answer:

1. You can either wait for OpenFOAM-dev to be updated sometime tomorrow, which hopefully will already include this bug fixed in it.
2. Or you can try running the following commands for updating the build:
   

   cd $FOAM_SOLVERS/heatTransfer/chtMultiRegionFoam
   sudo wget "https://bugs.openfoam.org/file_download.php?file_id=2203&type=bug" -O createMeshesPostProcess.H
   sudo -s
   source /opt/openfoam-dev/etc/bashrc
   wmake -j all
   wclean all
   exit

Thank you both
