I am wondering if there is a possibility to mark a part of body/part in DM to use it later as a register to patch in FLUENT?

For example. I have 1 body consisting of 1 part. I want to mark 3 different regions of these part so that I can patch them with different initial temperatures. Is this possible? How to do it?

Thats not what i am talking about.

Using Registers

The ability to patch values in cell registers gives you the flexibility to patch different values within a single cell zone. For example, you may want to patch a certain value for temperature only in fluid cells with a particular range of concentrations for one species. You can create a cell register (basically a list of cells) using the functions that are used to mark cells for adaption. These functions allow you to mark cells based on physical location, cell volume, gradient or isovalue of a particular variable, and other parameters. See Chapter  23 for information about marking cells for adaption. Section  23.9 provides information about manipulating different registers to create new ones. Once you have created a register, you can patch values in it as described above.

The question is: can I mark a part of 3D body to make it a register in FLUENT?
