Re: Surface Oxidation
Hi SteelOX, In your MICRESS installation directory, there is a directory "Examples" which contains different types of examples. Under subdirectory "Training" you find the file T011_Gamma_Alpha_TQ_dri. This is the example I proposed to start with. At the same place there is a subdirectory called "GES...

Re: Surface Oxidation
Hi David, You said before that you already have Thermo-Calc calculations. Just use the same database for MICRESS which you have used with Thermo-Calc. I think your newest version of the TCFE (e.g. TCFE9) should be fine. You cannot edit the .GES-file because it is a binary file. But in the GES_FILES ...

Re: Surface Oxidation
Hi SteelOX, ok, so essentially you could start with the quaternary system Fe-Si-B-O. Probably you want to simulate the spherical particles in contact to some atmosphere which contains oxygen, right? Then you need the phases GAS, FCC_A1, BCC_A2, HALITE, and QUARTZ. Which database do you want to use? ...

Re: Creating A Simulation
Dear SteelOX, for technical reasons it is necessary that the number of elements which you define in MICRESS is identical to the number of elements which are included in the .GES5 file. When changing the number or type of elements in a simulation, you typically need to modify also the .GES5 file. Bernd

Re: Surface Oxidation
Hi SteelOX: My first question in this regard is: Why do you use the example T009_CastIronDendriteNodules_dri as starting point? This example is quite specific for cast iron with formation of graphite nodules and uses the volume_change option because graphite is creating new volume due to the interst...

Re: PF simulation of Eutectic solidification
Dear Omid, Wish you also a Happy New Year. I guess that your question refers to the sum rule for entropy of transformation ΔS, which I wrote some time ago in this forum. In principle, this is a quite general property of scalar fields (like Gibbs energy) and their derivatives: There is a general path...

Re: High cooling rate and high resolution simulations
Hi Yongliang Ou, When you say that "the driving force of the dendrite tip varies a lot during the dendrite growth process", you probably mean that it is decreasing constantly to more and more negative values. I think the reason is a too low interface mobility. The value you set in the phase interact...

Re: Flash heating
Hi Kamran, When I copy the input you pasted above into a text file and run it with MICRESS Version 6.3 inside the MICpad editor, I get the following ouput: screen.JPG I am not sure why your screen looks different. Maybe it is because of the way how you started the MICRESS simulation. I strongly sugg...

Re: Flash heating
Dear Kamran, Welcome to the MICRESS Forum. For assisting you with your actual problem it would be helpful to have a description what exactly the problem is: Do you get error messages when trying to run the .dri file? Does MICRESS complain already during reading the input, or are there errors at a la...

Re: High cooling rate and high resolution simulations
Dear Yongliang Ou, Technically, it is very easy to increase resolution: you only need to decrease the grid spacing and increase the number of cells in x- and z-direction accordingly. However, your simulation domain is already huge, so I think it makes sense to have some basic considerations before. ...
