Hi Joshua, this is indeed by design and not a bug. The algorithm was designed to study the diffusion of particles in random velocity fields with a mean velocity greater...

Sounds exciting! Hello @opensourcecommunity, anybody interested? ;-) This could be a nice master thesis.

Hi Joshua, that is great to hear, thanks for testing the code! I hope I'll find some time this weekend to fix the problem you found.

That's a pity! But thank you so much for your script. Regarding the `mean` value, actually I'm not sure at the moment how to interpret it when applied to velocity...

Ah, by the way, in case you haven't done this already, you can significantly decrease computational time by using this line before compiling/ installing GSTools: `export GSTOOLS_BUILD_PARALLEL=1`

I just calculated the divergence of the equation given in the notes field [here](https://geostat-framework.readthedocs.io/projects/gstools/en/latest/field.generator.html) and the divergence is actually only zero, if the dimension of the cov. model coincides with...

Maybe I just need more sleep or more coffee... I just realised that I can make a tiny edit to the equations and it works... I think it should work...

Dear Joshua, I'm sorry for taking so long to come back the 4d fields. The last 10 days or so I just had too much things to do. Tomorrow I...

Hi, thanks for pointing that out, you are completely right. Would you be willing to implement a better criteria and create a PR?

Hi Michael-P-Crisp, depending on the application you have in mind, you could have a look at the already implemented [course graining procedure](https://geostat-framework.readthedocs.io/projects/gstools/en/latest/field.upscaling.html?highlight=upscale). For the application it is intended for, it...
