Hello,

I have a conjugate heat transfer problem, few electronic components being cooled directly by a fluid (immersion method of cooling) and i am using OpenFoam for this.

I am using toposet to identify different solid components inside the background mesh. Since some of the components are very thin (like a solder layer 0.1mm thick), i have to use a blockmesh with very high number of elements in each of the three axis. If the background mesh is not fine enough, toposet is unable to extract these thin solid components. I have to play with the backgroud blockmesh so as the toposet identifies all the solid cellZones successfully. Of course i can use snappy, but i do not think so i can get the same quality hexa mesh as given by blockMesh.

Any idea how to make sure that toposet identifies a particular cellZone successfully without using hit and trial with background blockMesh?

thanks

I am not sure I have understood correctly. Is your mesh from a blockMesh, or a different source? If it is a blockMesh, what happened to the cellZones from it?
