u4.63.03 Macro-command DEFI_PRES_EC8

Summary:

This macro-command constructs a formula for applying pressure fields to the walls of large reservoirs in the context of seismic verification by equivalent mechanical calculation according to Eurocode 8. To apply this pressure field, this formula should be provided to AFFE_CHAR_MECA/FORCE_COQUE_FO.
