Hello.
I am trying to create a 3D mesh where the overall volume of fluid is meshed with the trimmed cell mesher with respect to the 'laboratory' coordinate system, and a (body) surface in the fluid is meshed with the trimmed cell mesher with respect to a 'local' coordinate system.

Do I need to divide the fluid and surface into different parts/regions, or can I leave them as one part and customize the surface by assigning a separate coordinate system to the control surface?

Thank you.

Hi,

you have to use the method you described in the second of the two options.

Thanks for the reply!
I've tried the second option, but can't find a way to assign a local coordinate to the custom control(or surface control).
Could you please show me how I can do this?
Thanks again.

Hi,
Sure i can help you.

First create the local coordinate system. Go to Tools->Coordinate System->Laboratory->local coordinate system-> Right click and create new coordinate system

Next you need to assign this coordinate system to the Trimmer Mesh.
Go to the trimmer mesh continua. Under the property tree you can assign the desired coordinate system.

Thanks again, for the reply.
I have used Automated Mesh/Trimmed Cell Mesher under Geometry.
The coor sys for the Trimmed Cell Mesher is set to Laboratory.
I'd like to set the Custom Controls/Surface Control to local coord sys, but there doesn't seem to be an option.
In other words, I don't think I can set a different coor sys for a surface control. I believe it will be the same for the trimmer mesh under Continua.

Am I right?

No, only one coordinate system can be specified for the entire mesh operation.
