Error = 41

Hello,
my recent simlation throws a error message which you can see as a attachment. I have never seen it before. what is the reason and how can i fix this error?

"Unable to open file ... " during Simulation

Hello,
as a attachment you can find the error message, which occurs during my simulation. i have never seen such a message before.
The file, which should be opened is the file which should be written by the running simulation.

What is wrong with my input file? How can i fix this issue?

extremly small grains

Hello, As you can see in the attachment, in the last step, i got some pixels within the bulks grains. the problem is, when i want to analyse the TabK output, the avg. grain size is distorted, because micess detects them as very small grains. Is there a ability to delete them during post processing? ...

Re: Ferrite / Cemenite to Austenite

Hello Bernd, i have changed some of your mentioned points. The first problem is, in case of using thermocalc for all phase interactions, that the simulation time rises extremly. Furthermore, the result is worse. I cannot observe nucleation and the interfaces become thinner. what is my problem in thi...

Re: Ferrite / Cemenite to Austenite

Dear Bernd,
thank you for your reply!

I´m going to implement your suggestions in the file and try to get some results.

Ferrite / Cemenite to Austenite

Dear Bernd, after our personal talk about my simulation, i was able to make some progress, but i am still far away from my target. The problem is still, that tne austenite is not growing fast enough into the ferrite. Austenite formation is a diffusion controlled process, therefore i thought, that if...

Re: Ferrite / Pearlite Formation

Hi Bernd,
as attached you can find the ges file, dri.-file and images of the phase-output and fraction of cementite (frac3) output.
The Initial microstructure is too lagre, so i am not able to upload it. Is there another way to upload such large files ?

Ferrite / Pearlite Formation

Dear Bernd, i want to model the formation of an ferrite / pearlite structure with cementite as an unresolved phase - like in the examples. my approach was to use an ferrite / pearlite structure as initial, but to declare the pearlite grains as austenite. by cooling down this intial strucutre i want ...

Re: importing the initial microstructure

Hello, I am working on the same project as mehnoush. We were able to import an appropriate inital structure.Thank you for your help! But now, after starting the simulation process, we noticed another problem. We are developing a model for a steel with a (average) carbon content of 0.4 wt-%. It is cl...

Re: Initial Concentration

the second "problem" seems to be solved. i allowed diffusion of comp2 and prohibited diffusion of comp.1
But, nevertheless, what is the reason behind it, that i need a database to receive correct concentration data?
