Hello,

I would like to model 3D transient heat transfer in a solid. The geometry is made of a cube, which is drilled by a cylinder (that means, there is a hole).

I would like to compute the average value of temperature over this cylinder in the direction of the generating line (that means, integrating the temperature at each position on the axis over the circle perimeter), and then export it to a 1D-model, for each time step while solving.

Does anyone have any idea how to do this ?

Thanks,
Charles

Hi

check the doc on extrusion or rather projection coupling variables for your case

Good luck

Hi, Ivar, I've been staring at the documentation for 3 days. At least, any/all of the entries that show up if I type search "general projection".

I'll give COMSOL support a phone call tomorrow.... (This is my fault for working on COMSOL on weekends!!)

Are there any example models in the library that use general projection operators?

Regards, John
