Re: "Force automatic start values, GZTRBO error"

The default of the Gibbs energy system already is at version 6, not 5. I manually had to change this in TC before generating GES files.

Re: Error "Force automatic start values, GZTRBO error"

Soon we will also have this problem since we are upgrading our databases to TCNI12. Also, would it be helpful, if we change the preferred Gibbs energy system to version 5 in the Thermo-Calc settings?

Re: Nucleation model in MICRESS

Hi Bernd,

Is there a way to plot the number of nucleation events in MICRESS with time.

Re: Unstable diffusion

Hi Bernd,

Regarding point number 4: Do you mean deactivating off diagonal terms in all the elements like

2 1 multi gggggngg
3 1 multi gggggngg
.
.
.
Also do you recommend this to multi_plus as well?

Re: Heat Treatment simulation of Ni-alloy

Hi Bernd,

Are there any recommendation for selecting maximum time step for phase-field solver for isothermal HT simulations

Re: Data for further nucleation

so if one wants to define nucleation sites that is at least have certain distance between them at the beginning of the simulation what should be the path to take.

what I want is to guarantee that all my nucleation points will have a certain distance (which I can define) to each other.

Re: Data for further nucleation

Hi Bernd,

in the seed density model if I understood correctly, the seeds will be placed at the beginning of the simulation. so does this guarantee that we will get the distance between the placed seeds will be at least equal to the shield distance?

Re: Data for further nucleation

Ohh.. I have completely misunderstood the seed density model upto now. :) Now its clear.

Re: Data for further nucleation

Hi Bernd, so when you defined only one seed class with 1nm radius, then the seeds will be placed in the microstrucutre with that radius. if the ame seed class was defined with 10nm radius, then seeds with the size of 10nm will be placed. however since the concentration levels are not sufficient to f...

Re: Data for further nucleation

Hi Bernd

Perhaps I was not clear.

for example if I have a seed class that has 1nm radius, how can I define a critical adius of 10nm for that seed class so that the undercooling is not so high.
