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...

Re: The temperature calculation coupled with flow wheather consider the convective heat transfer

Dear Bernd I'm glad to hear from you.Thank you very much.In other words,the temperature change is just relevant to the thermophysical parameter in the 1D-temperature option? Fluid flow have not influence on temperature calculation at all? I don't kow how to contact with Ralf .Could you help me? Than...

Re: Restart options

Dear Bernd: Thanks a lot for your reply and I am sorry that I did not express it clearly. As you say, what I want to do is to add new nucleation seeds during solidification and let them grow, but I need to control the specific position of the new seeds in the liquid to consider the influence of the ...
