Appropriate element types are chosen from the NISA II element library to model the PCB and its components efficiently. A well graded mesh is created by maintaining standard aspect ratios between adjacent elements. The user has flexibility in deciding upon the mesh density.
Special care is taken to ensure a finer mesh in critical areas.
The mesh can be viewed graphically. Options such as rotating, windowing, etc., are available to the user. FEAP generates a file containing the finite element model along with appropriate boundary conditions, which can be used directly for performing analysis.
