hey guys,


i'm working on a project for laser beam welding and startet a case with a moving heat source on the surface of the two joint partners.


1. in my first step i created following three meshes with blockmesh:



- the two blocks, folder "block"


- refinementZone, which has the size of the movement area of the heat source


- laser




all my boundary faces have the type patch because i want to add convection heat transfer later (i dont know if thats the way its should be set but thats for later ). except the "side" faces of the refinementzone and the laser which have to be type overset.





2. then i merged them all in the folder "block":

mergeMeshes . ../refinementZone -overwrite
mergeMeshes . ../laser -overwrite

3. Now I have to do something with topoSetDict which i don't understand because I'm new.. this is why i want to ask you if the following way is correct:


- i will have to select the cells of the background, in this case the block

    {
        name    block;
        type    cellSet;
        action  new;
        source  regionToCell;
        sourceInfo
        {
            insidePoints ((X Y Z));
        }
    }

where i only have to put in a random coordinate that is inside the mesh of "block", right?


- ...


actually i am trying to do the same as in the tutorial "moving_cylinder" from wolfdynamics, where the background cells are selected as c0 and then the overset cells via inverting c0 (is this right? ):

actions
(
    {
        name    c0;
        type    cellSet;
        action  new;
        source  regionToCell;
        sourceInfo
        {
            insidePoints ((-10.999 -10.999 0));
        }
    }

    {
        name    c1;
        type    cellSet;
        action  new;
        source  cellToCell;
        sourceInfo
        {
            set c0;
        }
    }

    {
        name    c1;
        type    cellSet;
        action  invert;
    }
);
