## G. Computation

Clicking on the Solver button performs the ATILA computation, using the interface tothe program that sets the array sizes, calls up the subroutines for reading thedata files, computes the elementary matrices, assembles these matrices intoglobal matrices, solves the equations, and stores the results. At the end, thecomputation will provide a results file and files containing arrays forpost-processing.

After each run, the .lst file isavailable, containing the results (frequencies and eigenvectors, displacementand pressure fields, electrical impedance). It can be edited using the Edit result button. If desired, specific arrays are alsostored for post-processing.
