4. Execution phase

We check that the storage of the added matrices is done on a full profile.

We check that the self-mass added coefficients (diagonal terms of the matrix) are all positive. If not, an alarm message is sent for the user to check the orientation of the normals.

In the case of a mass calculation added to a generalized model, the user is informed about the copies of structural displacement fields in the fluid (number of values copied) and how to change the reference distance (DIST_REFE) is indicated.
