Re: Question on anisotropy of interfacial energy
Dear Feng, Please excuse my late reply, it seems that the notification function is not working correctly at our side. :( What you refer to is from the old Manual which has not been updated since MICRESS version 6.4. You are right that it is not correct what has been written there. Please note that t...

Re: Predicting of PDAS
Dear Sean, I think your approach of comparing the "stability" of the dendrite array before and after full overgrowth of the smaller dendrite is wrong. One should rather focus on the question whether a smaller dendrite can growth side-to-side with a bigger one, even if there are small fluctuations of...

Re: Temperature - profiles_from_file tool
Hi Mauro, If you mean with "200 data points" that you have 200 time steps with corresponding 200 temperature profiles, then you are right, and unfortunately there is currently no other way how to input that into the driving file. Do you have a proposal how we could simplify this procedure? If we wou...

Re: Predicting of PDAS
Hi Sean, In principle, the unit cell approach with KGT-calibrated interface mobility is a good basis for investigation of the PDAS. However, your conclusion, that the invariance of the tip temperature with changing PDAS (i.e. domain size) would indicate the stable PDAS value, is wrong. The tip under...

Re: 3D Simulation of direct solidification
Hi Sean, it seems you applied the factor of 16 also to the kinetic anisotropy coefficient, which is not correct: It should be only the static one! Thus, you are missing kinetic anisotropy. This, although physically viable, is not useful with phase-field simulations which are not extremely fine resol...

Re: 3D Simulation of direct solidification
Dear Sean, Nice to hear from you. Your simulation results look very nice! Let me try to start with the first question about the anisotropy coefficients. Unfortunately it is difficult to get physical values, and there is no general strategy what to do then. But on top of that problem, I think there i...

Re: using appropriate phase to mimic substrate layer in LPBF process
Dear Hanyu, Welcome to the MICRESS Forum! You describe a case where 2 phases can equally well grow as primary phase and thus compete with each other. This means, the question which one will prevail or overgrow the other strongly depends on the nucleation conditions for each phase. And the opportunit...
