Mesh Problem-Obstacle at mesh boundary
« on: December 19, 2018, 08:18:28 am »

Hi all,
I'm using the latest update of Pyrosim (2018.3.1210) and noticed something very strange. For parallel running of the simulation I divided the mesh in multiple meshes and noticed that Pyrosim appears to create a physical wall in some of the boundaries between meshes. I noticed a post from Tenzing in 2013 where the same phenomena is described, but back then the issue was supposedly fixed with a new update. Is there anyone else who encountered the issue as well?

That doesn't sound good at all. Is the wall you are seeing a visual difference, or does it appear on the FDS input file as well? If you have a model that shows the FDS input is being written incorrectly, please send a copy of the model to so we can get to the bottom of it as quickly as possible.
