Unknown patchField type cyclicACMI for patch type genericPatch

dasith0001 · July 12, 2023, 22:24

Hi Foamers,

The title says it all, I am getting the error by using cyclicACMI boundery condition in chtMultiRegionFoam with OF 10.

PHP Code:


			
Unknown patchField type cyclicACMI for patch type genericPatch

Any ideas to resolve this issue is highly appreciated.

I have attached the case file as well.

Thank you
Dasith

It means that you have specified a boundary condition type which is not applicable to the patch type. To apply cyclicAMI BC, your patch should be of cyclic ami type with other parameters of patch defined such as neighbouring patch, field transformation operation type, etc.

Dear foamers

I am simulating a multie-region problem in OF.

As far as I now, cht multiregion solver implements explicit approach for coupling the regions. (It modifies the boundary value at the coupled interface by iterations).
I want to know if there is an implicit approach for coupling.
Like making fvMatrix for different regions and assembling them and finally solving one general fvMatrix?

best,

Hossein

Hello Hossein,

Please avoid posting the same question multiple times on multiples threads.
I answered this here: solver for multi region?
