problem in solver
 

please find the attached one
i am facing problem while run the settings
can you please help me

Seems pretty obvious to me. You need more memory, or run it distributed parallel to share the load over several machines. Otherwise remesh with a smaller mesh.

hi
smaller mesh means?
do you mean number of elements and number of nodes ?
my current elements are 256413
nodes 449588

hi
please find the error

I would like to explain my problem

fluid is flowing in a multilayer porous medium which has different porosity and different permeability.

I have created multiple layer and created domain. i did interface fluid porous, porous porous, porous porous and so on .

the layer has 2micro meter , 10 micrometer, 200 micro meter and so on

Please help me where did i made mistake?

thank you

Rather than specifying this as different sub domains with different permiabilities it might be better to define the porosity and permeability as a function of location and use a single sub domain with variable porosity and permeability.

hi
I got your idea
can you please give a start or hint how to do it ?

hi
how to specify different porosity and permeability in a different layers of region
Please help to start my project

Thank you

hi
do you mean in the designmodeler , I have to create two solids, one fluid region part and other is porous region part.In cfx pre I have to specify different porocity and different permeabilty in a different layers( region) of the porous part . Am I correct?

Hi

How to split the single zone into multiple layers in cfx pre, for applying different porosity and different permeability

Thanks

Define your porosity and permeability as a CEL function, either an expression or an interpolation function. Have a look at the tutorials for how to do this. The free surface flow over a bump tutorial shows how to do this when they set up the inlet boundary condition.
