Add a new tranport model

semmana oualid · October 8, 2020, 07:21

Dear foeamers
I working on free surface flow cases for non newtonian fluids.
The rheological model I want to work on, is not integrated in any openfoam version.
I asking for assistance and support with examples and guides how to add a new model to openfoam and run the cases with that models.

The easiest way is usually to copy and rename the source code of the most similar model already implemented in OpenFOAM, then modify it as required.

I this case, https://www.openfoam.com/documentati...anIcoFoam.html could be a starting point.

Hi klausb,
Thank you for your reply.
can you assist me with free surface flow case with non-newtonian fluid.
Code or study case?

klausb · October 11, 2020, 07:49

Which "rheological model" do you want to work with?

Do you have a paper describing the model?

Have you ever compiled an OpenFOAM library or application?

Thank you and sorry for the late reply.
I am beginner user with basic programming knowledge.
I want to work with modified Bingham model.
Do you have any related guides or cases you believe that can help me.

Before you start reinventing something, would this implementation meet your requirements? https://github.com/fppimenta/rheoTool

Thank you again,
From the tool you mentioned, I shall learn from it and try to do my cases based on those solvers.
