CARTIF offers a wide range of technological services in design, simulation, verification and prototyping, covering the entire product life cycle for the structural system under study, from conceptual design to manufacturing supervision and optimization. Through this abilities we are able to reduce cost and time from the conception of the product / process until commissioning. 20 years in the automotive, renewable energy, chemical, building, infrastructure and and agricultural machinery industries allows us to offer our clients the guarantee of giving an answer to all their engineering needs. Simulation services we offer include verification according standard for static performance (including non-linearities as plasticity or large displacements), buckling analysis, mechanical fatigue and dynamic behavior. In addition, thermal problems (stationary and transient), insulation, duct loss and other aspects of thermal and fluid engineering can be addresed. Regarding the dynamic behavior of structures, apart from the usual abilities for modal and spectral analysis we can deal with transient and impact loading. Advanced instrumentation and techniques are used for model updating and characterization so modal mass and damping can be determined for every mode. This methodology allows us to propose and evaluate the performance of structural reinforcements or mitigation devices to improve vibration serviceability.

Available experimental techniques (static loading testing, operational modal analysis, etc.) together with the development of corresponding finite element model make posible to have reliable virtual models for assessment. Once the model is updated, issues such as semi-rigidity of the joints, expected cumulative damage in the lifetime, vulnerability, utility of embedded sensors, efficiency of passive control devices as TMDs or suitability of specific reinforcements can be addresed. For non-deterministic loading (wind, waves, traffic, human induced loading, etc.) other methodologies than the simplified proposals from the codes can be carried out. Multiphysics fluid-structure simulations via CFD are more and more accurate nowadays. These methodologies have been successfully used to estimate lock-in phenomena in large industrial chimneys, interference effects between close masts and waves in tanks under seismic loading, among others.
Besides our own developed applications, we have professional licenses for simulation software, either directly or through partners. These include ANSYS-Fluent, SolidWorks, or ABAQUS between the general purpose finite element packages and other more specific ones as LS-DYNA, ANSA, FEMTools, Artemis, PAM-CRASH, GH_Bladed, QUEST, ROBCAD, DELMIA, Magmasoft and other products from Dassault Systems and from Altair.
