Re: Today's question about diffusivity input

:? Hi! Well, again that's something that could do with a little bit more documentation... Actually, for backward compatibility reasons, by default MICRESS only uses the diagonal terms of the diffusion matrix (looking back on it, it might not be the most obvious choice, but there you are...), so "dat...

Today's question about diffusivity input

Guten Morgen!

Dose selection of "database_*" options for the Concentration Data section in driving file lead automatically the diffusion calculation to solving complete Fick-Onsager equation ?

Thank you very much for your explanation

I understood role of the parameters for Phase Field Data Structure in MICRESS driving file well.

Good point!

Guten Morgen! You are addressing a very good point, because this is something which has been improved for the new version which will be released very soon! Up to now (in your version) these two parameters specify the dimension of the iFace and nTupel list in MICRESS in units of Nxyz. That means if y...

What are roles of parameters for phase field data structure?

Guten Morgen! In the driving file, there must be two parameters as, # Phase field data structure # -------------------------- # Coefficient for dimension of field iFace 1.0 # Coefficient for dimension of field nTupel 0.5 I, however, did not see any numerical deviation of calculation result by changi...

Re: Input of latent heat needs to be changed!

Dear Deep, in your version, which is from June 2006, this change already took place! So your negative values are ok. Before, in older versions, people had to put positive values, what was somewhat inconsistent... In the .TabL output, in column 7, the temperature is written for each tab_log output. S...

Re: Input of latent heat needs to be changed!

So, finally what should be done?
shall i continue with the negative values..? :o

Moreover, how can I check with the .TabL output, if after plotting my graph shows variation of temperature which is uneven, i.e., increases at some steps and decreases for some.. :oops:

Input of latent heat needs to be changed!

Dear MICRESS users! We recently noted an inconsistency in the input of latent heat data for concentration-coupled calculations. Here an input of the enthalpies for all phases is needed, only the differences are evaluated. So you can input either values for the enthalpies if you get them from anywher...

Additional remark

Dear all,

just to clarify, the above said is true only for metallic anisotropy, not for faceted growth, and has to be specified in the phase interaction data!

input of static anisotropy changed!

Dear MICRESS users! Due to a reprogramming the range of valid inputs for the static anisotropy coefficient in the metallic anisotropy model has changed. The valid input range is now between 0 and 1 corresponding to no anisotropy and maximal anisotropy respectively. Before it has been between 0 and 1...
