Simulation of dust from landing on the moon

I'm thinking particles rather than smoke. Here's my attempt: I set up a fluid simulation (quick fluid) on a cube that I set to Inflow and animated "use flow" for some 40 frames, with ...

Simulation Cache is too heavy for SheepIt Render Farm

If you don't want to bake the simulation again (because I guess it took quite a while), there is absolutely nothing else than splitting it up. For future bakes, you might consider the following things ...

How does one create a particle cloud that collides like real smoke?

We should probably ask - What did you try and where did you fail ... :) Smoke Simulation Like in my comment simple smoke sim seems to handle your needs ... Vector visualisation ... Here is a slice ...

Smoke and fire quick effect offset from emission object

This happens because you must have run the simulation which then caches the results. Then afterwards you adjusted the location (moved) either the domain object or the emission (plane) object. The ...

Bugged flame appears only middle of the domain

You have set under Object Data Properties > Texture Space > Size X1 Y1 Z1, that is not correspond to your domain ... ... but it should be half of Object Dimension (size is measured from object ...

Can I disable my fire simulation from risign upwards

I assume you use settings like in the linked tutorial. The Flow Type is set to Fire and in the Shader Editor you set the Density in the Principled Volume shader to 0. Then I would set Gas > Heat to ...

Optimize Sim Cache

The simplest solution without changing the simulation would be to divide your render into several buckets of frames. Make several files with each a different frame range and provide only these frames' ...

multiple smoke simulations - independent of each other

You can control which emitters and effectors are used in each domain by placing each domains grouping of those objects into different collections and then specifying to only use that collection in the ...

Smoke simulation frozen

Can you add the file in your question? You can do this by going to blend-exchanges.com and adding the link in your question.

I can't see smoke in cycles

Smoke simulations in blender themself have no visible geometry, they simply define where a volume exists based off of various factors. To properly visualize this, you must define a shader for the ...

Smoke cuts off when emitter flow is turned off

Not an answer to your Q (for that see Gordon's A), just a tmp notes and alternatives :) ... one thing is - it would be more efficient to create smoke domains per jet not for whole object it could be ...

Smoke cuts off when emitter flow is turned off

As I mentioned in the comments, I cannot bake at a resolution of 512, but here is just a quick overview in which way the Resolution Divisions affect the appearance of smoke as well as how much ...

smoke simulation from different frame rather than from 1 to 250

many of the physics simulations should include all frames; for example a fluid simulation that doesn't include frame 1 will render a solid, obscuring volume within the domain for frame 1. Generally, ...

Can smoke have collision with an object created using the array modifier?

Yup! Just swap the order so that Array comes first in the modifier stack

Smoke Sim Still Blocky With High Resolution

To me this looks like 2 different issues. First the resolution stepping you mentioned, this is best seen at the front of your emitter where we see the fuel being created, and I believe the best ...

how to remove squares in smoke?

The squares appear due to the way that Blender renders fluid/smoke simulations. If you want your simulation to have a higher resolution (ie. everything looks smoother), then you can increase the ...
