Bird Strike - Project - 2

NNaveen Shirur31 Dec 2021

Aim : To simulate the bird strike in aero engine

Boundary conditions:

Following a consistent numbering approach 100000+ for nodes, 500000+ for elements, and 1000+ for the parts.

All other keywords should be numbered within 10000-19999 while following a range for each one. This guideline that the student is following should be included in the final submission

- The bird, casing, and the blades should be in different input files and there should be one main file referencing all the input files. The main file should contain only references. Control cards and boundary conditions should be there in another separate file. The reference include path should be such that the folder can be copied anywhere and it is able to correctly reference all the file and run the simulation.
