Issues regarding Standard Multi-Family House tutorial #11

Closed dhu5-utk closed 2 years ago

dhu5-utk commented 2 years ago

I am working on the Standard Multi-Family House tutorial. I followed the steps in the tutorial, However, the building will always collapse without deleting any elements and simulating earthquakes. I run the preprocessing one by one, and then I load the configure data and build. If I run preprocessing steps automatically, I will not have the load configure data options. Thank you for your time to take a look at this issue.

I have looked into it and apparently here are multiple issues going on that needs to be fixed from our side. The file currently works best with the FM version of Blender you can find here: http://kaikostack.com/fracture Use the FM mode for simulation to avoid the problem for now, the third tutorial shows how that works.

Thank you so much for your quick response. I tried the FM mode and it works great. I have one more question, How can I visualize the cavity using the cavity detection tool? I select all the objects and run "detect cavities" and nothing appears.

KaiKostack commented 2 years ago

You need to select the "BCB_export" object containing the debris heap then the cavity detection tool should work and generate a new mesh with name "BCB_Visualization". If I remember correctly multiple elements are not supported yet, only FM-based results within one object container.

Very much appreciate your answer. The cavity detection works well for FM-based results. BTW, I saw your amazing video posted on youtube regarding the Miami building collapse. I am wondering if the building model used in that video is available to the public. Thank you for your great work and for making the BCB tool publicly available.
