where can i find Combustion example for CfdOF??
Re: Combustion
Check this example for OpenFOAM solver: https://develop.openfoam.com/Developmen ... rtmentFire
Re: Combustion
thank you kindly!
I was trying to avoid using early 20th century tech of coding
batch processing sheets of OpenFOAM! I am on it thou!
in the meantime FreeCAD "sim" of combustion "dies" in solving process after few seconds
without any information other then "something went wrong"
having no way to ignite the mix I try to boost temperature of gasoline to hypergolic levels?????

Re: Combustion
Methink Multiphase selectiion has something to do with it??????

Re: Combustion
The multiphase option in cfdof-wb uses the interfoam solver (see controlDict file after case writing).
InterFoam is mostly used for free surface flow:

Re: Combustion
Actually addressing my problem?
the run-away condition was fixed by Changing "Time Step Control"/"Time Step" to 1.00 in CfdSolver
not sure how it got to be zero?
So the QUESTION STILL REMAINS?
How to program combustion, what solvers??? and what other setups?????

Re: Combustion
the solver that will do combustion is - reactingFoam -so now the question is can freeCAD handle it?
or will I have to recode OpenFOAM in CFDAnalysis????

Re: Combustion
Unfortunately CfdOF does not support reactingFoam. You would have to set up the case in OpenFOAM as suggested by @NewJoker, although writing and modifying a case created by CfdOF should make life easier than starting from scratch.
Re: Combustion
thank you kindly! it makes much easer to plow thru!
I will "write case" in "Analysis control"
then I will select "Edit" button and recode the sheets!
I will use https://www.youtube.com/watch?v=BnykhP8olUk&t=744s as a guide!
Question will I have to mess with "CFD Mesh" edit???

He is running a 2D analysis. Have a look at his mesh.fungnow wrote: ↑Thu Nov 18, 2021 6:05 pm thank you kindly! it makes much easer to plow thru!

You can do the same with cfdof. See boundary definition, constraint.
I will try to rebuilt the YT-example in FC.
