Grid Project Title:Mighty North



Purpose of Project:Produce mesh for modeling Mighty North test which was a pile of machined limestone bricks with a hole in the center of the pile for an explosive test.


One  quarter of mesh with triangular elements refined to approximately eight triangles along the edege of each brick.

Design Criteria:

Summary of Project:
The design criteria have been met. The region and mregion commands were a bit tedious to create since each brick needed to be defined individually. This would be a good candidate to use something like Python to create the LaGriT input file.

Initial mesh with minimum number of nodes that captures problem geometry.



 


Rivara refinement which only adds a point to the center of each material.




Some refinement and smoothing.
