Compiling Your Own Custom OpenFOAM Solver, Part 0

All code can be found at: github.com/lor...
DESCRIPTION:
Here we will take an existing solver, pimpleDyMFoam, and simply rename it and compile it so that OpenFOAM recognizes the newly named solver. This may sound trivial, but making your own solver typically would follow this procedure of copying and existing similar solver and adding modifications. Here, we will simply omit the modifications.
The new solver, mySolver, and the original from which it is copied is contained in the 'solvers' folder.
The tutorial case upon which we will try our new solver comes from the pimpleDyMFoam section of $FOAM_TUTORIALS.
OUTLINE:
-Rename the following files with your new solver name:
-Solver folder
-Solver main source file (.C)
-Application and Source description in the main source file comment header
-Change names in 'Make/files'
-Run 'sudo bash' to become super user. This is necessary because you might get permissions errors when trying to create your new solver executable in $(FOAM_APPBIN) as specified in 'Make/files'.
-Run 'wclean' and 'wmake' in main directory of your new solver.
-Run 'exit' to leave 'sudo bash'.
-Run 'mySolver -help' to show that your new compiled custom solver is recognized!
-Run the tutorial case 'mixerVesselAMI2D' to show that your new solver works! The modifications:
-In controlDict, change 'application pimpleDyMFoam' to 'application mySolver'
-In controlDict, change 'endTime 5' to 'endTime 1' for a shorter run time.
NOTE: we have copied various '.H' files into the main directory of this tutorial because the specification of the includes in 'Make/options' are such that these headers need to be in the directory above the solver main directory (via '-I..'). You can of course change this, but this is how it is in the default pimpleDyMFoam solver included in $FOAM_SOLVERS.

Good job! keep it up

good friend, I have tried and I have not been able to create my own solved.

[@ardacetiner9968]

I have ubuntu 20.04.1 LTS and OpenFOAM 8. Without "sudo bash" I got an "permission denied" error at the end of compiling process as you mentioned in the video. But when I use "sudo bash" command, this time it comes with "command not found". What should I do ? Thank you!

i had similar issue, Following action i did to overcome with this issue please check if you have installed make package with below command -which wmake This command should return the path to wmake if it is installed correctly. If it doesn't return anything, wmake might not be installed or the path might not be set correctly. if it is already installed then with following command, you can give permission -ls -l /opt/openfoam9/wmake/wmake -chmod +x /opt/openfoam9/wmake/wmake

Gracias, pude al fin utilizar uno para resolver reactores tubulares en 1D, Ex. 6: Tubular reactor - Run it, en linux mitn 19

[@OpenFOAMTutorials]

If google translate is correct: "Thanks, I was finally able to use one to solve tubular reactors in 1D, Ex. 6: Tubular reactor - Run it, in linux mitn 19" then glad to be of help!

Ah utilice OpenFoam6, Gracias.

I am implementing a vof model, can I ask you for an advice ?

At 3:05: what makes the "wclen"?

[@OpenFOAMTutorials]

I don't think I built wclean here, but if you do "which wclean" you can find where it is located.
