Technical+Issues

This page is for GENERAL technical issues rather than individual simulation queries.

The discussion regarding Domain Size refers to 3 images that are required for adequate understanding of the concepts being explained. The wiki only seems to allow images to be placed on Pages, not within Discussions. Therefore, I am placing the 3 images on this page for use in the discussion regarding Domain Size.

Top down view of gap **

Top down view of gap with Block actor on. The cells seem to be about twice as large as your gab so there is no way the gap will ever be seen as a gap even if you were to reposition the domain.

Top down view of gap with block actor and X cells changed to 256. The cells are now slightly smaller than your gab, but because of the specific position of the model in this domain, the very edge of the building occupies the cell that would otherwise be in the gap. In the end this simulation sees the geometry exactly like the last one with X cells 128.

Top down view of gap** with block actor and X cells changed to 256 and domain slightly moved to -0.11 in the x direction. By moving the domain ever so slightly i was able to position the blade and the building so that the gap fully occupies a cell. This simulation now recognizes the gap.

Door Width A. To emphasize how the position of the domain can affect a simulation. No longer talking about the gap between blade and wall. This is now all about door width. Here is the domain in one spot. **

Door Width B. Here is the EXACT same simulation with the domain just slightly moved. Nothing else has been altered. Now the door width is nearly half of the previous simulation.
