7. Summary of results

The purpose of these tests is to verify the correct calculation of the mean value of the deformation field using the macro command OBSERVATION. The reference solution is analytical for the static response, the harmonic response, and the transient response.

This test case also validates mixed field observation (DEPL, VITE,…) with a single call to the OBSERVATION operator.

The differences between the solutions obtained with Aster and the analytical solutions are very small. For the results from a modal calculation, a non-regression test is proposed.
