Fluent - 3D Mesh
 

Hi guys ,
This is my first post I am new to ANSYS and i am working on blood simulation but I face a problem of meshing and i need help
How to determine my mesh method ? I mean how to decide is hexacore or sweep better for my case ? my second question is how to evaluate it and know if it is okay with my goal or not ? I can't find user manual for Fluent Meshing that's why i am stuck in this point .
I appreciate your help
Thanks in Advance

Hi Omar,

In your Ansys workbench there is tab of "Help" on top.
Click on it and on "Ansys Workbench Help", it will open up a window of help viewer.
On the left side there is "table of content", if you scroll down you will all type of guides including DM, meshing, Fluent User's guide!

Hope it helps

Cheers

hi there,

I think in general, sweep is always better since it gives very good quality structured mesh. Having said that, sweep is not always possible. It really depends on the complexity of your geometry. Of course, you can always divide your geometry into smaller blocks such that each of these blocks can be swept.

I read in other threads that hex-dominant method may sometimes produce very bad tets cells in between the hex's to fill the space, so keep that in mind, and avoid it if possible.

I tend to go with a combination of sweep and tets, cut out as many blocks as possible to be meshed using sweep method, and use tets to fill up the remaining domain. I find it to be a good balance between cell quality and cell count.

Good luck.
