Nonlinear finite element assembly and solution on GPUs.

Libraries Required:

• CUDA
• ParMETIS/METIS
• OpenGL
• GLUT
• GLEW

Runtime Operation:

• Mouse 1: Rotate

• Mouse 2: Zoom

• Mouse 1+2: Translate

• Shift + Mouse 1:

Create draggable 'keynode' at nearest visible mesh node

• Drag Keynode:

Apply boundary forces

• Ctrl + Mouse 1:

Delete keynode

• 'c': Center

Centers the view on the mesh

• 'r': Reset

Returns the simulation to its initial state. Useful after an element inversion causes NaNs to wipeout the simulation

• 'p': Pause/Resume

Pauses the simulation

• esc: Exit

Exits the simulation and closes the visualization window

• 'R': Record

Saves each frame of the animation as a binary RBG file called ######.bin. WARNING: Large, uncompressed files and slow writes.
