Re: Synchronizing data outputs

Hi Moritz, the grain data output (TabGD) for each individual grain is given at every main output time. That cannot be influenced. The summarizing grain output (TabK) is given each time when the overall number of grains changes. It can be parameterized with the options 'standard' and 'extra'. Seems t...

Re: Local Dislocation Map

I checked newest version 7.1 and found a bug in these input routines. 2D ASCII input for dislocation densities might not work at all. Do you get mean recristallisation energies of zero for all grains afterwards? This would mean your version has the same bug. I recommend to use a VTK in ASCII format....

Re: Local Dislocation Map

The wrong separator could be the problem.
Usually, we use a space separator. I never tested this with a comma.

Re: Local Dislocation Map

The data input loop is Z-Y-X, i.e. the inner most loop iterates over the cells in X direction. See also the training tutorial 'importing inital grain structures' on the 2nd day. The VTK format explained for grain structures is the same as for dislocation densities. Grain IDs or densities are both sc...

Re: Local Dislocation Map

Hi Carl,

have a look at the example T11_04_ReXLocalRecovery.
https://micress.rwth-aachen.de/download.html#examples

The used VTK for dislocation densities are given in a ASCII format.
The only trapfall may be to give the DIMENSION in number of corners, not as number of cells.

Best regards,
Ralph

Re: Data analysis ragarding grain size

Hi Moritz,

in principle, all necessary data about grains to analyze grain size distribution is given in the grain data output (TabGD).
It is an open TODO to provide some distribution plots in DP_MICRESS.

Best,
Ralph

Re: System resources for calculations

I mean using the parallel version of MICRESS, e.g. MICRESS_par_TQ.exe, and setting the number of threads at the end of the driving file.

Re: Microstructure from file

Hi Khusbu, I am not sure how you configured your input and how your property file look like. Do you apply a property block for each grain? Anyway, your output shows a only single with grain ID 1. Now, I understand your question above. Looks like your microstructure file only contains a single value ...

Re: Microstructure from file

Hi Khushbu,

the read grain IDs are sorted in ascending order.
The properties are questioned following this order.
