changing cell dimension during simulation
Hello Bernd, I am trying to simulate coarsening of cementite particles in Fe-C system using MICRESS. For that I need to start with small particles first, thus I have to use smaller cell size. However, at the later stage of coarsening when the cementite particles have grown, I would like to change th...

Re: How grain boundary diffusion works
Then, the value for f is 1/8 not 8 as you mentioned above Am I right?

Re: How grain boundary diffusion works
Thank you Bernd,
Then, the approach that I presented above is also correct. The only difference is that I used Tanh function to present phi instead of sinus function.

Re: How grain boundary diffusion works
Dear Bernd,
Are you aware of anyone who can help me in more detail on that since I am going to report that in a paper.
Best regards,
Hamid

Re: How grain boundary diffusion works
Dear Bernd,
Thank you for the response. Honestly, I am looking to see how 'f' was calculated. How did you come up with f=8 as the normalizing factor?
Thank you
Hamid

Re: How grain boundary diffusion works
Dear Bernd,
I could not add '+' to the equations. Thus I had to make an image out of my question .
Thank you,

Re: cell dimension
Dear Bernd, I used small scale model to see diffusion controlled reaction and I came more or less to the same number of the mobility. Below you can see the simulation and the corresponding results. When, I look into the driving force values at the interfaces (ferrite/austenite and cementite/austenit...

Re: cell dimension
Thank you Bernd, Actually, I did similar sort of calculations for the following situation, a rim of austenite around carbide particle, below. Then I changed the mobility for austenite interfaces (both with ferrite and cementite) systematically and the results is shown below. As you can see in my sim...

Re: cell dimension
Dear Bernd, My simulation only deals with carbon diffusion and the reaction meant to be diffusion control. The mobility values for austenite interfaces are chosen to be high enough for that purpose. The interfacial energies are all about 0.5J/m^2. I will send you a copy of my input file via email. I...
