Hello! I am going to simulate plumes for a telecommunication satellite using SPT100. However I always got geometrical errors when I convert to Numerical Kernel. If anybody worked with SPT100, can you please tell me the mesh sizes you used for the inner circle and outer circle points and the central point ??
Thank you!
Message by Mehmet Balta:
I tried with much bigger mesh sizes, and I saw that problem that solver was getting stuck, was caused by small mesh sizes. Thank you anyway. Does anybody know what kind of mesh sizes SPIS likes to work with? Because I have another project and I do not know how to arrange the sizes.
Thank you!

Guys I would really appreciate if someone who has worked with or have an idea about the SPT100 or a similar thruster replies. My problem is that when I simulate SPT100 alone, it perfectly works. But when I implement it to a Satellite body, it always give error. Problem is not with the geometry. If you think SPT100 as a disk. outer and inner part of it are the same satellite body. So please let me know why there is always error, could it be about mesh sizes or something else?

Hi,
Very hard to tell in the general case.
Could be mesh size or mesh shape indeed. We have seen problems like this when you have triangles that are very stretched out or when you have very small gaps between CAD objects.
Try to mesh with different resolutions and see if it changes the result. Also read what is displayed in the log console (or in the debug.log file that is at the root of SPIS) to know when the kernel hangs.
What version of SPIS do you use?
Kind regards,
Benoît

Hi,
I use the version 5.0.1. I have errors when I save the project with global parameters.
Here is my model:

I also tried with assigning the middle circular surface as another surface group with the same properties as SC Body. On the figure it is a part of SC body. I also dont know how I should do it.
