Re: Predicting of PDAS
Hello Bernd, thank you for your input, good to know that the first step of my approach was not so wrong. I have read your paper, and I think the model with the distance criterion is quite good. If I apply it to my example, I also get meaningful values for the PDAS. But i have also an question about ...

Predicting of PDAS
Hello everyone, I am trying to make a prediction of the PDAS using a phase field. My approach here is: 1. calculate the tip undercooling using the KGT model and a pseudo binary phase diagram like its done here . 2. Select the simulation domain so that the width corresponds to half the dendrite spaci...

Re: 3D Simulation of direct solidification
Hi Bernd,
I must have misunderstood.
With the higher kinetic anisotropy, I have a dendritic form again.
Thank you very much
Sean

Re: 3D Simulation of direct solidification
Hello Bernd, i have tried to implement the harmonic_expansion model to the simulation, but now i have a problem with the formation of the dendrites. As you can see, solidification does not take place in the typical formation of dendrites in the cubic system. I have other directions of growth in the ...

Re: 3D Simulation of direct solidification
Hello Bernd,
thank you very much for your comments and suggestions.
I'll try out the implementation and will get back to you if there are any problems.
Many thanks already,
Sean

3D Simulation of direct solidification
Hello, I want to do a 3D simulation of direct solidification and have already set up my Driving file. The Simulation works quite well, but I have still two questions about it. 1) Is there a standardised procedure to determine the two parameter: # Anisotropy of interfacial stiffness? (cubic) # Anisot...

Formation of a thick interface during dendritic growth
Hello, I´m using MICRESS 7.1 and I have a problem while simulating dendritic growth wiht the bridgman approach. I want to simulate dendritic grwoth of an Ni-Base superalloy (CM186LC). My Problem is, that during the solidification, a thick interface and holes in the dendrites are forming. I Have test...
