Hi
is it possible to solve multi layer medium by laplacianFoam solver? |

If so, the answer is no for the default laplacianFoam but it is very easily modified to allow this. The diffusivity (called DT) in laplacianFoam.C is a dimensionedScalar (same value for every cell); you could change this to be a volScalarField that you read from the case: this would allow you to set a different DT for every cell; you could set layers using setFields. You may need to be careful if there is a large discrete jump in DT across an interface, as the normal gradient would not be defined; however, the default method may be fine depending on what you are interested in.

Hi Phllip thanks for your kind response, How can i implement complex shape like closed curve ( NOT ordinary shape like circle ...) by setFields or funkySetFields? is it possible to do? i want to simulate heat transfer in human eye as i attached its picture. Regards, Mohammad |

Hi Jam,
The convenient way for generating mesh for the mentioned structure can be Gambit or GridGen, and then transfer it to OpenFOAM format. Cheers shakil |

you are right, But every layer of mentioned structure has different value properties e.g. thermal conductivity and i want to implement these properties by funkySetField. any idea? Regards, jam |
