 This example outlines how to use VDB implicit files to infill lattice on a brake geometry in Grasshopper. This example also outlines how to run simulations on the infilled geometry. This example outlines how to use VDB implicit files to infill lattice on a brake geometry in Grasshopper.

 To reference a vdb file that was modeled with implicits, place a file path object and set the path to the vdb file. To reference a vdb file that was modeled with implicits, place a file path object and set the path to the vdb file.

 Next, reference the geometry where the loads and restraints will eventually be place. Since this is a brake pedal, the load will be placed on the top surface of the foot pad and the restraint will be on the inner surface of the larger hole. The lattice infill files will need to be connected to an intact volume read component. At this point, the grasshopper canvas should look something like this:  Next, reference the geometry where the loads and restraints will eventually be place.

 After this, the workflow for setting up boundary conditions, the stress solver, and solver settings is similar to [[wiki:sns:intactgh:ex_1|Ex-1: Stress simulation of a bonded assembly]]. The part is made of Aluminum 6061 and the rest of the simulation conditions can be seen here: After this, the workflow for setting up boundary conditions, the stress solver, and solver settings is similar to [[wiki:sns:intactgh:ex_1|Ex-1: Stress simulation of a bonded assembly]].
