Merge problem
1 Attachment(s)
When I try to merge an unstructured mesh and a structured mesh, for some reason it doesn't work. I included an attachment with an impression of the geometry. Does somebody know how to solve this?
The error it gives is (as visible in the attachment): " I am trying to include edge 81107 62911 but vertex 81107 isn't even in the region 1 unable to include quad 168283 (81100 62912 81107 62911) " I tried to play with the following things, but it didn't work: Add or remove surfaces at the interface. Change face association at the interface for the blocking. I know that the mesh sizes don't match that well in this case, but that should not be a problem. Has somebody an idea? Thanks in advance, Gerrald |
rules for merging tetra with hexa:
keep it simple... one surface which will be your interface. Merged surface must share a perrmeter 100% Both meshes must be projected to that perrmeter About size: 0.7 (hexa) to 1 (tetra) is best From Simon tip and tricks I have some free time, we can investigate together the project if you don't mind sharing your project... |
Thanks for the help, I now simplified the geometry using the create topology command, and it seems to work.
What do you mean by investigating together? I can send you the geometry, it is just a geometry from literature which I want to use for validation. Gerrald |

That would be nice. I wanted to try by myself, also because I need to get used to ICEM, but I still don't manage to fix it. I always keep the troubles of geometry which seems not to be closed and those kind of errors.
In the hyperlink below you can find a .tin file of the geometry and a description of the geometry. I need three impellers who can rotate in a baffled vessel. For this reason I made a cylindrical interface around each of the impeller, and I want to apply a MRF approach to these interfaces. I also need to include free surface flow, so on top of the cylinder I made another volume which I could fill with air initially. Finally I also need a place to inject some tracer during a transient analysis in order to track the concentrations. The article describing the geometry is (I use the bigger geometry from the file): CFD simulations and experimental validation of homogenisation curves and mixing time in stirred Newtonian and pseudoplastic liquids from Montante et al. A screenshot of the geometry (T=48cm) is presented in the dropbox as well. The vessel is baffled with four flat baffles of width T/10. Due to holidays I don't have access to Icem coming two weeks, but I can still correspond. Thanks in advance, Gerrald Gelderblom Click here to view MONTANTE. |
