Complex network stitching

[skydivine22]

Hi!

I'm trying to stitch 3D cubic networks together to simulate different regions of micro-porosity in a main macro network. What I have in mind is that I want to first delete the pores and connections at the region where I want to add the cubic micro-networks, and then stitching a micro-network there. The examples provided only detail stitching a donor network onto one of the 6 boundaries of the main cubic network. I am wondering how to stitch a donor network in the middle of the main network( the space created by the deleted pores/throats). I have attached a very crude 2D drawing to provide some visualisation.

Thanks so much

Andy

Judging by your use of the word 'donor' I see that you are already aware of our 'merge_network' function in the topotools module? This function kinda works, but was written a long time ago so may be rough around the edges. It does get unit tested on each update, but not exactly 'stress tested'. Anyway, can you confirm whether you've tried this function or not, and if so what problems your having?

BTW, a better way to generate multiple scales is to start with a fine network then choose pores to merge into marco-pores. This bottom-up type approach just seems to work better. We used it in this paper.

Hey!

So yes, I’m not exactly using the merge_network function but the stitch_network one. I was following the example and it shows stitching on only one side (e.g. top boundary of the network with bottom boundary of the donor”). I’m wondering if it’s possible to stitch the donor to the interior of the main network as opposed to the boundary. I have not seen this paper actually so will give it a look tomorrow. Thank you so much once again
