Misorientation: phase_interaction & redistribution_control

Dear Bernd, On this occasion, I am looking at the implementation of the 'misorientation' functions which account for the reduction of the interfacial energy (Read-Shockley) and mobility (Humphreys) as function of the misorientation angle between grains. May I ask you about how the misorientation bet...

Re: Seed-density and seed-undercooling models

Dear Bernd, Thank you for all your comments and feedback. I apologise in advance for spamming this forum with this long message but many comments and questions resulted from the previous discussion. Regarding the interface energy, as a first approach, I estimated this physical value through the prop...

Re: Seed-density and seed-undercooling models

Dear Bernd, Thank you for your message. I was sure that I clicked 'submit' but it seems that the message did not go through. I have sent it now. I have just checked one of the running simulations after removing 'ordered 2 1 2" but still getting, --> Force automatic start values initialisation failed...

Re: Seed-density and seed-undercooling models

Dear Bernd,

Thanks for your prompt response. I have removed the line "ordered 2 1 2" from the input file and simulation is running. In the meantime, please find attached in a pm the input file.

Many thanks,

Mauro

Re: Seed-density and seed-undercooling models

Dear Bernd, Thanks for your detailed message. I have shortened the temperature range for checking nucleation of FCC_L12#2 (gamma-prime) accordingly, but still getting: --> Force automatic start values initialisation failed, error = 2 interface FCC_L12/FCC_L12#2 Thermo-Calc error 1611 MICRESS error 2...

Re: Seed-density and seed-undercooling models

Dear Ralph, I have been looking at several existing examples to explore more on how to implement the '1d_temp' field (A002_AlCu_Temp1d) and 'connecting points' (T014_Gamma_Alpha_Stress and T021_Grain_Growth_Profiles) tools. Furthermore, I also read through the great work published by Kumara et al. (...

Re: Seed-density and seed-undercooling models

Hi Bernd,

I meant SLM and/or welding but actually DSC type of simulation would be actually interesting to perform likewise.

Many thanks,

Mauro

Re: Seed-density and seed-undercooling models

Hi Bernd,

Is there any example file relevant to thermal-cycle simulations that I could use for guidance in MICRESS? Otherwise, may I ask you on what steps shall I follow to perform this?

Best regards,

Mauro

Re: Seed-density and seed-undercooling models

Dear Bernd,

Yes, I meant extracting the central coordinates. While simulations running in the background, may I ask you if it is possible to produce temperature profiles in MICRESS by solving the transient heat transfer equation?

Best regards,

Mauro
