Hi,

I have a loop which searches for intersections of arbitrary vectors with my boundaries (Patches) using indexedOctrees.

pointIndexHit pHit = octree1.findLine(outsideP, insideP);

To save computation time, I want to create the indexedOctrees needed for every patch outside the loop and store them.

Problem: I can't manage to create a List. This code

Foam::List<indexedOctree<treeDataFace>> octreeList1;
forAll(patches, patchI)
{
    const polyPatch& polyPatch1 = patches[patchI].patch();
    treeBoundBox allBoundingBox(polyPatch1.points());

    const indexedOctree<treeDataFace> octree1
    (
        treeDataFace(false, polyPatch1),
        allBoundingBox, // overall search domain
        8,      // maxLevel
        10,     // leafsize
        3.0     // duplicity
    );

    octreeList1.append(octree1);
}

results in

error: no default constructor exists for class "Foam::indexedOctree<Foam::treeDataFace>

Do I need to add a default constructor to the indexedOctree class? Or is there a simpler way of doing what I want?

Thanks,
David
