Can’t produce any traces from the seeds placed over the intake. There are traces produced if I place the seeds randomly on the enclosure.
Also, using isovolumes to have a velocity mapping shows what I would expect… so, the CFD calculation seems to be correct, except the particle tracing won’t produce any visual results.
project is here: SimScale
Could you provide more explanation? In other simulations I did not need any cutting plane, and the traces were visible. Why would it be needed in this particular case?
As it seems, I still struggle to understand the logic of this particular software, because at the moment many things don’t make sense. So, an explanation of WHY would help me move forward.
*I see you enabled all the faces for geometry. If the reason why you mention the section plane is to see through geometry, then I’m letting you know that I used a view and transparency which did not require this artifice. My issue was why I could not see the traces being generated where they had to be, but if I moved the seeds in other location, the traces were generated.
Thanks @Retsam
To reiterate: please look at the image below: seeds are in place, but no traces being generated.
However, when I opened the project this morning, it looked like there were generated (but again, opening the results didn’t show them)
Traces not being generated from seeds:
This is what I could see when opening the project this morning:
… is this a bug of Simscale? Am I doing something wrong? Is the most frustrating when results are not consistent, because I cannot pinpoint what I’m not doing right.
Hi, @derei
I believe this is a known bug (see this thread for reference, with a similar geometry as yours).
Cheers
@Ricardopg thanks mate! Creating a section plane just below my inlet and placing the seeds on it fixed the issue!
Much appreciated for finding this for me!
