Hello everyone.

I am a college student trying to replicate an ANSYS model found in literature but I am struggling. I have successfully created the geometry, but I am unable to generate a mesh that accurately resembles the target model. Below is the model I am trying to replicate:



And this is the closest I have come:







I used to method found here to generate the above mesh.

Any help would be greatly appreciated.

Thank you for the quick response. I watched the video in its entirety, however, I really didn't understand it or how to apply it to my model. It appears that I'm supposed to create an inner cylinder in ANSYS Design Modeler and somehow that will change how the mesh is created?

Based on another thread, I've managed to achieve this:



Which is closer, but I'm not quite sure how to get the exact number of nodes/etc that I need. I do know that there needs to be 16 layers of inflation. I was wondering if there was a way to view the number of nodes only on a face? My cylinder is a 3D solid, but I'm trying to match the number of 2D nodes before I match the number of 3D nodes.

right click on faceboundary and get info

It appears that the advice you have given me is for ANSYS ICEM. Is there anyway to achieve this in the ANSYS Mesher?

ok. You have to slice your geometry.

Could you possibly expand on this? I've watched this tutorial but I am still struggling to determine the proper procedure. I've attempted to slice of one of the faces, but I am not succeeding.

search forum. this has been discussed no of time

Do you happen to have a specific thread in mind? It may be the terms I'm searching, but I haven't found anything that answers my questions.

I've successfully separated the faces using the "surfaces from faces" option in the Design Modeler, however, it creates an overlapping mesh: one for the surface body and one for the solid. The original reason why I wanted to separate the face was so I could match the node count to the model I'm trying to replicate. It appears that separating the faces to get individual node counts is not the way to go about it.

this face split command wont help you. you need to slice your whole volume to get five parts. where you can apply map mesh

Thank you very much. I was able to successfully slice the volume into five parts as you said. This is my progress so far.





I am having some trouble applying inflation. I am unable to apply inflation when I use a "sweep" method and the inflation looks like this when I use a "multizone" method.

good work. You are on right track.

Thanks. Any advice on fixing the inflation?

Hi
I read the Thread you implied and tried to make exactly what you achieved in your picture. Here I repeat the text I wrote and asked for help. I'd be thankful if you teach how to make it.
Copied text:

I want to make exactly the mash you made, but my geometry is a little different. As you see I have a 90 degree bend (made by "revolve").
2 problems:

1- when I use face meshing it doesn't appear as a "Mapped Face Meshing" although I made the square and 4 lines in the middle (by using Tools>splite face), and in the setting for face meshing, the "mapped" option is set as "yes". how did you exactly made it that way?

2- when I insert a mesh method as "multizone" it first gave me an error, something like: could not automatically find source. Then I manually added it (in the picture in RED color. again it gave a new error which you can see in the same picture: "Multizone found free blocks in swept body"
Please help me with this.


my automatic mesh with Inflation ( not what I want, too messy)

This is face I chose for Mapped face mesh, Which doesn't actually turn out as "MAPPED face mesh"

the error with "Multizone Method" after selecting SOURCE manually.

I will do my best to answer your question in your own thread. Please only post your question once and preferably not in someone else's active thread.

Thank you very much. Sorry for doing that.
