Re: Simulation of dendritic growth in 3D

Hi Yaozu,

Just go to "File/Export window content as dataset". Then you can switch format to vtk and select the outputs you want to join in the .vtk files. Further options should be self-explanatory.

Re: Simulation of dendritic growth in 3D

Dear Yaozu, I have never seen what you describe. Obviously, the .phas image which is shown on the right side corresponds to an earlier time step, because you can see the small grain in the lower left corner. However, the annotation text below the image shows the correct time of 1.2 s. What do yo mea...

Re: Simulation of dendritic growth in 3D

Dear Youzu, What you observe essentially is tip splitting (taking into account mirror symmetry in x direction). In principle, tip splitting can be a physical phenomenon, but in your case it is certainly numerical. The detachment of the dendrite arm which grows horizontally could simply be due to the...

Re: Simulation of solidification of Gamma prime alloy during SLM process

Hi Chamara, I could not find anything specific which would be wrong in your input file, apart from the general difficulties with MC carbides which I mentioned above. In such cases, there is no other option than to try out what could help. Essentially, I tried several modifications in order to preven...

Re: Simulation of solidification of Gamma prime alloy during SLM process

Hi Chamara,

I got your files and are running them and to try some ideas what could help. It takes some time for running, so I will tell you about the results on Monday...

Re: Simulation of solidification of Gamma prime alloy during SLM process

Hi Chamara,

Like I have outlined recently, MC carbides are one of the most difficult type of precipitates, and many parameter settings affect their behaviour. Maybe the fastest way to get further is that you send me the complete input files so that I can run the simulation myself.

New functionalities of MICRESS 7.0

Dear all, A number of new functionalities have been included into Version 7.0: As an alternative to the “classical” multiphase-field model, a reformulated version handles volume changes during phase transformations in an approximated manner. This is e.g. essential to simulate graphite growth in cast...

New input syntax

Dear all, One of the most obvious changes in MICRESS Version 7.0 is the new input syntax. Apart from some technical necessities, the main reason for these changes was the improved consistency and intuitiveness, which we hope will make your working with MICRESS easier. One of the main drivers for the...

Two old papers on TQ-coupling I discovered recently

Hi all, While searching for literature I recently stumbled upon two conference papers of mine from 2000 and 2002, which essentially mark the beginning of TQ-coupling with MICRESS. For unknown reason, these documents have been forgotten and not been included in our list of References . The two public...
