Questions & Troubleshooting / Can I acheive this in Meshmixer?
« on: February 12, 2018, 05:20:54 PM »
Hello everybody,
I'm an absolute newbie to Meshmixer and I was wondering if it has the capability to modify geometries that I'm interested in. If you guys think so, I'll learn how to use Meshmixer, if what I need is not possible to do using Meshmixer, could you guys suggest alternative methods/software/techniques? Details of my problem are given below:

The Geometry:
I've attached an image to this post. The geometry you see has been developed from MRI scans of patients with heart defects.

The Problem:
In the image, you'll see a portion which has been highlighted in a dashed box. In the patients I'm interested in, this portion is a synthetic graft and stays the same size, whereas the rest of the geometry outside of the dashed box are blood vessels that grow. So what I need to do is to uniformly scale up the portion outside of the box, while keeping the portion inside of the box constant and at the same time not break the mesh. I need the scaled portion of the geometry and the unscaled portion of the geometry to remain connected by smooth curves, if possible. I intend to use the final geometry to create a volume mesh that I can use for a finite element simulation.

Thanks in advance!
