After new update the mesh will disappear in many cases ....

After 0.3 update the mesh will disappear in many cases, even with same code and same STL model the mesh is not generate and there is no object to simulate.
Here an example with previous build:

Same code, same STL, ... with latest build:

i test it with at least 10 different models, if there is an small issue in model it will not work anymore but in previous build it was much more stable and better. also the performance was a bit better with previous build as well (very small but better)

Hi Erikca. It's not possible to debug the issue with the information you shared. Can you please share a repro code?

[Ericka-dev]

Hi, simply use this STL model as reference and replace it in windtunnel_3d.py with previous and latest build. you may need to adjust the size of grid so it match the object something like 860, 300, 180.
even in initial frame you will notice the difference,

@mehdiataei @Ericka-dev
Same issue here, with the new update, many cases fail due to a mesh error that was completely fine in the past version.

I am going to take a look at this issue. Thanks for reporting it @Ericka-dev @BFMEntertainment
