Hello

Sorry for my English.
In an animation two half shells are rotating, drawn in red by me.
This was added in a compositing program.
I just want to create the half shells how to get the look created in Redshift.

Thank you very much

Many thanks for the support

I will test the scene.

Have a nice weekend

Thank you for your answer.
I don't know if this is usual, but I would like to continue bilingually from here on.

The Fraunhofer animation serves as a template.
I would like to illustrate the following.
In gas welding, the gases acetylene and oxygen are mixed to produce a welding flame. If these gases escape in an uncontrolled manner and a spark is created, an explosion occurs. The gases are contained in pressurized gas cylinders.
When the gas escapes through the small outlet opening, the outlet cone is very narrow at the beginning and then becomes wider.
I cannot adjust this in Pyro.
It also looks too much like smoke.
Due to the pressure in the cylinders, the exit should be much more even and faster.
The animation from the Fraunhofer Institute comes very close.
The good thing is that I have been working very intensively with pyro over the last few days. But I haven't achieved what I want with pyro.
Perhaps there are other possibilities within C4d.

Sorry for the confusion. I have corrected my answer, it was inappropriate.

Thank you very much for the answer and the provided scene Dr. Sassi

I have spent many hours and worked through many tutorials.
The biggest problem is starting the simulation.

Thank you very much and have a nice weekend

Thank you for the answer Dr. Sassi
The video shows the effect I want to achieve from 0.12 onwards.

Please excuse my English.

I would like to take advantage of your help.
Gas is continuously flowing out of two gas cylinders.
I cannot adjust this in Pyro.
Do you have any ideas?
