Dear Mauro,

Thank you for sending your input files as PM. Unfortunately, the .ges5-file is missing, so that I cannot run it. Please send it.

Dear Mauro, The first error is obvious, you have to use the keyword "columns": profile-500.txt columns 1 2 The second error message should come with a preceding message line, which could either be: - "Unable to open file" - "Error while writing to file" - "Unable to close file" Thus it can be anythi...

Dear Jane, The Kim-Kim-Suzuki (KKS) phase field model is a fundamental phase-field approach which uses separate compositions for each phase and assumes equal chemical potentials (more exactly diffusion potentials) as equilibrium condition. Although we in the MICRESS group developed our equivalent ap...

Dear Vitoria, It is really difficult to find a reason for the different behaviour, which obviously can be boiled down to seed-type 2, where fcc-phase is nucleated to the bcc/cementite interface, and which appear to grow systematically slower in the Linux case. Of course, we cannot rule out completel...

Dear Vitoria, It would be interesting to know if the orientations of the grains are the same in both cases, or whether different misorientation relations are there. This should be visible in the graphical .orie-output. Further, as a consequence, the interface mobility (.mueS) should also be the same...

Dear Vitoria, That is difficult to say, because the different phases have different orientations which are not visible here. And from the .log-fie I see that you have blocked various misorientations, so it is clear that the different nucleation types, having different parent-relations and acting on ...

Dear Vitoria, This unfortunately is true, because the Windows and Linux operation systems use different random generators, and random numbers are used in MICRESS to create random seed distributions as well as random noise on the critical nucleation undercooling (if requested). However, your experien...

Hi, A diffusionless or "massive" transformation occurs if the driving force for transformation is so high that the pile-up of all elements at the interface can be overrun. Then, the front velocity can be much higher than in the diffusion-limited case. For each element, depending on the physical back...

Dear lv,

The message means that the .geoF-file has not been written yet. This can be the case if the writing of the t=0 output has not been finished yet. If the 3d-geometry is large, and you are writing over network, this can take a while...

Dear Jane, Going through the input file I have found several issues: 1.) You are using FCC_A1 and FCC_L12 simultaneously in one simulation. This does not make sense, because FCC_L12 is identical to FCC_A1 but additionally accounts for order-disorder transformations, and should be absolutely avoided....
