Re: Numerical accuracy of double obstacle model

Hi Bernd,

How are you?
Your suggestion is very useful. The fd_correction can overcome the problem completely.

Numerical accuracy of double obstacle model

Hi there, Long time no post. I recently implemented a very simple 1D recrystallization between two grains. I found, the model has a 90% accuracy, e.g. the simulated interface velocity v.s. mobility x driving_force if I use a coarse grid; whereas if I decreased the grid spacing, the interface does no...

Re: MICRESS 6.0 released

Hi Ben, do you think of a logarithmic color scale? It is not implemented, yet. We will discuss whether that might be useful or not. It is possible to export virtual EDX scans as a table (comma separated file), see file menu of the plot window. On these files you can use other tools (e.g. GNUplot) t...

Re: MICRESS 6.0 released

Hi Bernd,

Thank you for your reply.
Sorry, i am lost in your explanation on effective phase. Anyhow, It cannot be used as an initial phase, right?

By the way, is there no "logarithmic display" option in DP_MICRESS 7.0.0_beta?

Re: MICRESS 6.0 released

Hi, Bernd I am trying to use the new features of MICRESS. I have some questions. what's multi-obstacle phase field equation? How to use the option "effective phase"? What's special of it? Previously, when I construct an effective phase, I just devised the thermodynamic data such as dS, slope, refere...

Re: entropy difference between two phases

Hi Bernd,

The periodic boundary condition has no problem for 1d. Now I got correct results. I guess the problem is in the input of initial concentrations.
But for some reasons, I got correct results now.
Thank you.

Re: entropy difference between two phases

Hi Ralph, Thank you. Now everything is OK. Does MICRESS_TQS 6_001 version work well with paraTQ? I got wrong thermodynamic data: for example, c0 is not consistent with what's obtained from TC. later on, error 604 in QPARAD CALFUN. Total concentration greater than 1. Here is part of my setting. If I ...

Re: entropy difference between two phases

Hi Bernd,

Eventually, our TQS version is running well. Thanks a lot for help from your group. :)

But I got a warning about GES5 file format incompatible with TQ library.
I generated the file with TCCS. It should be no problem.
Could you please double check it?
Thank you.

yes, that's it! Did you try already?

Hi Bernd,
:cry: not yet.
We got MICRESS and TCS servers installed on two computers, and are figuring out how they can communicate.

Re: entropy difference between two phases

OK. I got it.

I need using ParaTQ with TQS version.
