Dear Team, Can we simulate exact PCB cooling part which includes conduction and convection physics also we should be able to see flow streamlines and temperature profiles over solid structure. Please share any tutorials files as when I try I receive attached error. Thank you.

Hello Dheeraj Singh

If, in your model, there is any face that is in contact with both Fluid and Solid faces, please use the imprint tool between the solid faces . 
You may find a similar tutorial on the Getting started- Thermal tutorials page.

There are some CHT examples on the Getting started - Fluids tutorials page as well.

Hello Subashni

Thanks for your response. 

I have gone through all tutorials. 

But this imprint feature doesn't work between enclosure(fluid domain) and solid(heat sink, heat source). This imprint feature works only for solid - solid(between heat source and heat sink). 

In my work, forced convection happens due to air flow over PCB(heat source, heat sink). Can you please share this kind of sample models or tutorials.

If possible we can discuss this over call.

 

Regards,

Dheeraj

The same example that you require of a PCB is in this page.

It is performed as a Thermal simulation and not CHT.

Check out the third video in the Player.

Hello Subashni

Could you please provide update on this.

Thanks in advance.

If that example is not clear to you we can discuss this over Teams call at 11AM tomorrow (14th Sept).

Please let me know your availability so that I can send you the Teams meeting link
