Re: Simulation of dendritic growth in 3D

Dear Bernd: It may because my computer is running out of memory. I will try to display the results on another computer. As the same to you, I write results in native format, but I don't know how to use DP_MICRESS for converting them to .vtk format to view with Paraview. Could you please tell me how ...

Re: Simulation of dendritic growth in 3D

Dear Bernd: Thanks for your help! I change the position of the initial seed to (0.0.0), then the tip splitting disappears. However, there is a problem with the result. When I observe the output, the .phas and .frac show nothing while .conc can display the simulated result, as shown in the picture. T...

Simulation of dendritic growth in 3D

Hi Bernd, I have performed a 3D simulation of dendrite growth with your help. I put the initial seed of the solid phase at the lower-left corner(x=1,y=1,z=1)of the simulation domain and let it grow freely with a temperature gradient and cooling rate. However, after some time I find the structure is ...

About the output of 3D and 2D

Hi, Now I'm simulating the three-dimensional silidification process of steel via MICRESS. However, when I use the 'vtk' option, I can only get the 3d output which should be opened using specialized software, and I cannot observe the intermediate output. If I using the 2d option, I can observe the ou...

Re: Primary Dendrite Arms spacing (PDAS) prediction

Dear Bernd:

I'm so sorry that I was busy with other projects some time ago and ignored the forum....

Now there are the input files (driving file and .ges5), and would you give me more detailed advice.

Re: Primary Dendrite Arms spacing (PDAS) prediction

Dear Bernd: Thanks! In my simulation for directional solidification, in order to match experimental conditions I set the constant cooling rate and temperature gradient and choosed moving_frame. The domain is 1000*1000 μm and resolution is 1μm. For initial microstructure, I use the systematic method ...

Re: Primary Dendrite Arms spacing (PDAS) prediction

Dear Bernd: I am interested in the PDAS(Primary Dendrite Arms spacing) and SDAS(Secondary Dendrite Arms spacing) prediction during solidification process via MICRESS. I have established the binary and ternary phase field model of steel, but all the SDAS I got through simulation is less than the expe...

Coefficient of thermal expansion in austenite transformation

Hello, I would like to ask a question, I want to simulate the process of austenite to ferrite transformation, in the simulation of the coupling of the stress, so in the material data for elasticity recommendations plate need to fill the austenite thermal expansion coefficient . The coefficient of th...
