extrudeMesh: Wedge extrusion with positive AND negative angle
I would like to know if it's possible to use the wedge extrusion of the extrudeMesh utility with at the same time positive and negative angle value.
For example a symmetric wedge extrusion between -\theta,\theta would just be fine :D.
Is there some hidden option to control this in the extrudeMeshDict ?
Of course it's possible to split this in two operations but I've already got quite a lot of sub-domains that I have to stitch with stitchMesh utility and would like to avoid to use stitchMesh too much.
Does anyone know if it's possible to do this kind of wedge extrusion ?
Thank's for your helpful contributions
I've modified the wedge.C source file to be able to use the wedge extrusion of the extrudeMesh utility with an angle between -Angle/2 and Angle/2 where Angle is the angle value read in the extrudeMeshDict file.
Of course it doesn't work :D.
My problem is that after the extrusion of the original patch in one direction (-Angle/2 <= \theta <= 0) I'm unable to start the extrusion in the other direction (0 <= \theta <= Angle/2) from the same original patch: it always starts from the last extruded layer.
Some pictures below will illustrate the problem clearer.
Here are the modified parts of the wedge.C source file :
How can I start again from the original patch (the one which is extruded at first) ?
Any ideas ?
I honestly suggest that you take the simpler road on this case:
This works, unless you want to perform this sort of manipulation for some other reason than using the resulting mesh as a wedge.
