The mesh motion is implemented already when the displacement is in x,y, and z directions and is applied to a tube. I have attached a simplified schematic so I can explain. I have this tube,...

It is a moving mesh approach that you can find described here "10.1016/j.medengphy.2018.04.014" I have attached a picture of the...

I do not think the parallel movement would fix it, as I do not have a hand on the displacement that I am aiming for. I have a complex cylinder-shaped structure with two inner surfaces...

Replies: 20 Normal vector variable of curved surface Views: 4,213 Posted By Louisgirucl Follow-Up On Normal on node Dear pled, I am looking to use the same method as you are using, I want to displace nodes following only one Normal. So you can confirm from your experience that using Normal X will displace the...
