What' What's next next … Working on two main ideas in which Code _Aster has a central role: 1) web based SHM with Real-Time FEM updating; 2) civil structures: web-FE modeling and design.
What' What's next … next We are looking for collaboration with software developers and R&D WHAT WE OFFER: departments to Cooperation Cooperation in r n resear search ch pr projects ojects and knowledge transfer and knowledge transfer improve our knowledge and WHAT WE’RE LOOKING FOR: capabilities with Suppor Support and exper and expertise in Code_Aster ise in Code_Aster related lated pr procedur ocedures es Code_Aster.
