Blender Version
Broken:
blender 2.93.1

Short description of error
fluid simulation oftenly crashes blender when changing the source value on in the initial velocity tab and over all general quarks such as the simulation stops working halfway through if i use a source value which is close to 2
Exact steps for others to reproduce the error

I can't reproduce this issue. what are steps to reproduce? Does it happen when I type in number and press enter?

Can not reproduce the issue with 2.93.1 (03d5c8b4ed commit date: 2021-06-25)

Simulating the scene does not cause the crash. Could you please clarify the exact steps to recreate the crash?

Also: Please attach system information generated from help menu (Help -> Save System Info)

System Information:

Graphics card : AMD Radeon(TM) 535 ATI Technologies .```

(ops, did not notice the Richard's comment. I better refresh the page before commenting :p)

i dont know how to attach system information

but i have a b450 asus tuf motherbored and my gtx 1070 ti is on the version 466.11 drivers i also use a 550 wat psu a my computer has never required more wattage i dont overclock and i have a stable 2tb hdd and a 256 gb ssd

The video you provided is helpful in that I can believe, that this could be genuine bug. But it is very hard to follow. In best case you should try to identify set of steps that would cause crash each time, so crash can be reproduced by developer reliably. In some cases this is not possible though, but that is hard to know in advance.

In Blender, click on Help -> Save System Info, but please follow these steps instead:

Download latest alpha from https://builder.blender.org/download/daily/ and check if this bug is present.
If bug still happens, run file blender_debug_log.cmd. There will be 2 files created, upload them here.
Open debug output file, and check if at the end of file there is path to .crash.txt file mentioned. upload this .crash.txt file too.

sorry for taking so long here is my system info system-info.txt

blender_debug_output.txt unfortuntly there wasn't a crash txt but this is the blender debug output

Sorry, I missed notification here.

I will re-check, but still set of exact steps would be helpful.

Can confirm here (simulation stops at around frame 50, closing blender then crashes)

Seeing this in the console:

RuntimeError: GridCg::iterate: The CG solver diverged, residual norm > 1e30, stopping.
Error raised in extern/mantaflow/preprocessed/conjugategrad.cpp:562
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "<string>", line 169, in bake_fluid_data_4
  File "<string>", line 164, in bake_fluid_process_data_4
  File "<string>", line 136, in liquid_adaptive_step_4
  File "<string>", line 221, in liquid_step_4

But this has been reported before, see #87975 (Mantaflow simulation stops and crashes at the end of the bake (or when closing blender): The CG solver diverged, residual norm > 1e30, stopping.), will merge these reports
