residual stresses of thermal spray coating process (COMSOL v4.0a)

[AlDeak]

Hi,

I'm trying to simulate a thermal spray coating process, with COMSOL Multyphycis v4.0a.

My model is a multiple-layer Fe3Al / Al2O3 gradient coating on carbon steel substrate. I use a 2D axisymmetric geometry.

3 steps are needed to simulate the deposition of each layer :
- pre-heating of the substrate (or pre-deposited layer) (h=300 W/m².K and T=3000K)
- deposition of the coating layer
- cooling-down

The coating is composed of 5 layers.

I use 6 physics "Heat Transfer" for the thermal analysis. I would like to know how to use the final temperature of layer N as initial temperature of layer N + 1 .

Thanks for your help!

Are you doing a transient analysis?
This is normally done through boundary conditions on the solid.

Yes I'm doing a transient analysis.

I have found a way to solve my problem.
I use one solver to solve each step of my process.

So there are 10 solvers and the initial values of solver N+1 is the solution of solver N.

It's working well!

I used to work in a rocket factory with a guy named Alex Deak. Structures wizard. Any relation?
