The general FEM solution process is given below:
1. Input Geometry & Processing Conditions
2. Generate Initial Guess of Velocity Field
Single step:
3. Calculate Element Behavior Based on Velocity Field
& other variables (strain, temp, etc)
4. Calculate Force boundary conditions based on Velocity Field
5. Assemble and solve the matrix equation
6. Calculate the error
7. If error is too large, apply correction to velocity field and go to
step 3. Otherwise, continue to step 8.
8. Update Geometry
9. Calculate temperature change for this step
10.Calculate new press velocity if necessary
11.If stopping criteria has been reached, END.
otherwise, go to step 3 and repeat the process
