If you are not familiar with UDFs, why not just set the region as a separate volume (it can be thin) and then just use the GUI to specify a constant source?

Hi,

when i tried to create volume it shows an error:

cannot create ACIS body. Is this an open shell?

what can i do plz advice. its a 2d problem so i don't have few faeces to stitch together.

Thank you for your time.

Ok, in 2-D make, your region for the heat source to be a separate face and apply a heat source in that region.
