New publication on MICRESS phase-field model
Hi all, The "homoenthalpic" paper is now ready: B. Böttger, J. Eiken, M.Apel, Phase-field simulation of microstructure formation in technical castings – A self-consistent homoenthalpic approach to the micro–macro problem, J. Comput. Phys. 228 (2009), 6784-6795. I can send you a personal copy on requ...

Re: stabilization
Dear mtoloui, did you already have a look on these threads: Reference1 Reference2 Actually, this option is referring in first place to small grains, which still do not have a cell with full fraction. "Stabilisation" means to assume a reduced curvature in this stage instead of the phase-field curvatu...

Re: Categorization
Dear Sunny, In order to throw several grain to the same grain number, they have to have identical properties. If the phase in question is anisotropic, you could nucleate them with a random orientation distribution, and categorisation would be practically impossible because they have all different or...

Re: 1d_temp
Dear sunny,
I have sent you the files by email and I have also put them to the temporary download area in the MICRESS homepage so that everybody can access them:

Phase 0 in solid state transformations
Dear all, I got several times the question why in simulations of the gamma-alpha transformation the phase 0 has to be included even if it is not needed, and sometimes even physical paramters have to be given for this phase. The reason has to do with the past of MICRESS as a solidification tool. At t...

Re: 1d_temp
Dear sunny, the mentioned example is on the redistribution CD for versions 5.404 and newer. Unfortunately, it is still not on the list of examples in the downloads area of the MICRESS homepage. but here is it! I'll send you a PM with the file and the additional input files you need to run the exampl...

Re: failure?
Dear zhubq,
Nevertheless, MICRESS should not behave like that! I am still interested in seeing the driving file in order to know exactly how it fails!
Thanks!

Re: failure?
Dear zhubq, This error definitively should not occur! I have never seen itbefore, but, if it is reproducable, it seems to be connected to the initialisation of the boundary conditions in the subroutine initRand. Do you use strange boundary conditions or do something wrong in the input which is not p...

Re: nucleation issues
Dear Raghav, what I do not understand is how you can perform a solidification experiment at 973K if the liquidus temperature is 1227K! Even if you would pour the melt (which initially has to be above 1227K to be completely liquid) into a mold of 973K, you would get nucleation at a higher temperature...
