Dear Math2Market,

I heard that it is possible to rescale the simulation domain and the voxel size not only by integer values, but also by decimal numbers. Could you tell me how this can be done?
I would really like to run simulations faster this way, without losing too much accuracy.

All the best,
Caroline

Dear Janine,

Thank you very much for this detailed reply! I received the email and will try some simulations with it.
Reducing the data points also makes a lot of sense. Thank you! I look forward to the results.

Best,
Caroline

Hello Janine,
Yes, I run a homogenized simulation. I only have GeoDit 2024. Is there also any way to speed that up?

Thank you for the link to the video! I will try that. Does GeoDict contain ready-to-use text files with concentration-dependend values, of does the user always write their own text files? I am simulating NMC622 as active material for my cathode.

Best,
Caroline

Hello everyone,
I am running charge simulations for my electrode structures of 500*500*544 voxels à 100 nm. When using constant parameters for the electrolyte, the simulations take about 3-5 hours. When using concentration dependend lithium ion diffusivity and ionic conduction, the simulations repeatedly take 95 hours. Is this difference in time normal? I know simulation time depends on the computer hardware, but maybe you can tell me, if a factor 20-30 increase is normal.

On that note: is it also possible to use concentration depended values for lithium ion diffusivity for the active material? Just out of curiosity.
Thank you!
