4. Execution

It is verified that the parameter for which the filtering is performed exists in the input data structure mod. If this parameter is not filled in, a fatal error is output. On the other hand, for the keyword IMPRESSION, if the parameters MASS_EFFE_UN_ * are not filled in, an alarm is only emitted.

At the output, the product concept resu_mod must not be empty, otherwise we end up in a fatal error.

We also check that all the concepts mode_meca_* or mode_gene are of the same type and that they come from the same initial problem (same matrices).

After filtering the interesting modes, we check that they all have a different modal position. If not, an alarm message is sent. To remove these duplicate modes, you must reuse the EXTR_MODE command and activate the NUME_MODE_EXCLU operand.

To date, it is not verified that the data structures of the mode_meca_* type correspond to the same standard.
