Re: .korn file
Hello, I got the following message from Raghav: Hello Dear Mr. Bernd, I tried to upload the attatchment in Micress forum but i wasn't successful. But i have the questions for alloy Stabilor G with ref. to the role of kin. coeff. in the simulation results that i have in the file. Schönes Wochenende R...

Re: .korn file
Dear Raghav, "korn" is german and means "grain". The .korn file is a graphical output containing the numbers which are assigned to grains in a consecutive manner when they are defined in the initial grain structure or nucleated during runtime. The grain number is not a physical property, but allows ...

Re: Numerical parameters
Hi Antoine, of course there is no general rule. If I start a new calculation in the field of solidification of metals, I start trying with about the following values: interface mobility (cm4/(Js): - solid liquid interface for solid solution phase (e.g. fcc-liq): 0.1-0.01 - solid-liquid interface for...

Re: Numerical parameters
Hi Antoine, I did not say that one "should" use very high resolution and high interface mobilities! I was just stating that if we could afford a very high resolution we would just have to set the mobility high enough and everything would be fine. But in practically all cases we cannot afford such a ...

Re: Parameters for latent heat?
Hi Antoine, If latent heat is used in a 2D MICRESS simulation, a 3D correction may be necessary, depending on the symmetry of the simulation domain. If all three spacial directions are equivalent like in equiaxed solidification, the 2D shape corresponds to a projection of the 3D structure to the 2D ...

Re: Effects of averaging of the driving force
Hi Antoine,
Of course, you are right, it was a misprint, the average solutal undercooling is decreased!
Sorry for that...

Re: Post-Processing errors
Dear Raghav, This type of errors occur if there is a convergence problem in the calculation of the quasi-equilibrium – in your case between the phases 0 and 2. It can happen for example if the system is very far from local equilibrium and ranges in the thermodynamic database are accessed which are n...
