I am encountering this error, Error 1100: No un-cut fluid cells adjacent to DEM_MI staging area.
Unable to setup the discrete solids mass inlet for BC:1
I have not been using an STL file, and everything is generated within MFiX, including the mesh generation; I have seen in other forum posts that this usually happens because of the use of importing the STL files, which isn’t the case in this problem.
I am getting this error when I am reducing the mesh size to 5cm.
I would be grateful to know how to resolve this and get some insights.
I am attaching the case file for reference. Forum_validation.zip (55.6 KB)
Thank you for your time, I look forward to hearing from you soon.
Yeah, I checked the case, because the fluid cells attached to particle mass inlet have zero volume fraction. In another words, those cells are empty cells, they don’t have fluid.
And this is a very special case when you used imax = 340, jmax = 240, kmax = 100 (those are number of discretizations in each direaction). I tried using imax = 341, jmax = 241, kmax = 101 and it can run.
My guess here is that in a very special circumstance, the search algorithm to find the fluid cell id attached to particle mass inlet returns wrong id values. But I need to check on that.
Thank you for your response.
I was wondering if there are any intermediate solutions at the moment to resolve cases like these.
Please let me know if there are.
Unfortunately we have to modify the source code and come up with a better search algorithm, this issue not only applies to GSP but also other dem model. Right now you can do is to vary the mesh size. Some sizes will work and some sizes will not. In your case, mesh size a little bit smaller than 5cm will work.
I will keep you posted if we find a solution for that.
