Hello cfd-online members,

currently I'm encountering yet another problem... I want to split a mesh I created via snappyHexMesh into two regions using the setSet utility. This was no problem until I recently changed from OF v7 to OF v1906 (the ESI version). There must be some kind of change in the syntax and I'm not able to figure it out. I have been looking through dozens of threads in this and another forum and also the documentation, but I couldn't find anything that solved this.

I created a simple case as an example, I have a cubic basic mesh and add in a cylinder. The cylinder is supposed to be one region and the rest of cells is to be assigned to another region with the setSet utility.

What I would have done in OF v7:

- blockMesh
- surfaceFeatureExtract
- snappyHexMesh
- setSet -batch system/setSetDict

In OF v1906 this works until the setSet part. Here I tried to execute my commands individually (without the -batch) and tried to figure out where I was going wrong, but even with the "help" function I couldn't figure it out.

I never posted a case on here before, but I uploaded my data to a github, I think it should be open for anyone to see. https://github.com/vince-cfd/split_mesh

Thank you already,
Vince


EDIT: Was able to solve it. The Syntax wasn't changed, it is just that setSet wouldn't refer to the latest timestep, but to time 0. Therefore, if I just use SMH -overwrite and go on as I was used to, it works.
