Hello all,
I am trying to simulate spinoidal decomposition using phase-field method. Most of the literature I could have given equations in dimensionless form. However, I intend to solve them in dimensional form.
Can someone suggest some reference where this problem has been dealt in dimensional form.
It will be really helpful.
Thanks
Deewakar
Dear Deewakar,
I am not sure if I get your question right.
Considering spinoidal decomposition, the Allen-Cahn type evolution equation is generally used for the modelling of the temporal and spatial evolution of the phase-field. In this case, the phase-field characterizes the local volume fraction and can be employed to analyse the morphology and distribution of phase constituents involved. Thus, the unit of the phase-field is volume fraction. What do you mean by dimensional and dimensionless form?
Best regards,
Julian
Dear Julian,
I think that the question is about time and space scales.

Hello
Thanks for your kind reply. I am trying to solve problem in dimensional form by virtue of some data available, hence the need.
However, I managed to get the good parameters. Thanks for your kind help.
Thanks
You can take dimensional data as data using natural units https://en.wikipedia.org/wiki/Natural_units
Then dimensionless number are all physically unit data
Here is an intro example: Article Phase field study of interfacial diffusion-driven spheroidiz...
