• DYNSOL

features the latest technology for solving structural dynamic analysis of beams, shells, membrane, cables and solids, using the finite element method. Furthermore, this module can perform assessment calculations, based on naval and offshore engineering standards.

• NAVAL

improves RamSeries capabilities with some specific naval utilities. For example, it is possible to study the behaviour of a hull structure with stiffened shells (with standard naval stiffeners, like HP), not being necessary to model the whole set of stiffeners. It is also possible to define wave loads, using the wave significant parameters relative to the hull. An automatic equilibration of the ship in that conditions is performed, adjusting sinkage and trim. This allows a complete structural analysis of the hull, with the self weight loads, specific weights loads and the loads due to the pressure of sea water.

• PLASTICITY

includes several material constitutive laws in order to model complex model behaviour. Among others, it is possible to simulate the structure assuming shell elements with J2 plasticity for the material with the following characteristics:

Isotropic hardening (linear, exponential, linear+exponential)

Kinematic hardening (linear)

• IMPACT

One of the most significant developments of RamSeries is the implementation of contact-impact algorithms which permit the analysis of many problems in engineering. The contact-impact algorithm implemented in RamSeries is the so called "Node to Node approach". In this approach the potential contact nodes are predefined by the user.

• COMPOSITE

As for composite materials, RamSeries allows to study laminated shells, and also composite material naval stiffeners. One important improvement is the capability of setting predefined standard laminate sequences giving each ply direction. A key feature here is the possibility of viewing the critical strains and stresses in each of the laminated material plies or tissues. The Tsai-Wu criteria is also applied for obtaining the security factor (global, and per ply).

• PREPOST

includes a fully integrated pre and post processor environment specifically designed for the creation and adaptation of analysis geometry, as well as the later visualization of results. The pre-processing part allows the generation of complex geometries defined by typical CAD entities, such as NURBS or COONS surfaces, through the variety of tools available. In the same way, it is able to import standard CAD files in IGES, PARASOLID and DXF formats among others. PREPOST offers a consistent and intuitive interface for definition of boundary conditions, material properties and other data. Data definition is performed at geometry level, being independent of the mesh/es used in the analyses.

• TDYN

is an environment for computational fluid-dynamics (CFD), multi-physics simulation, and fluid-structure interaction calculations, based on the leading stabilized finite element method (FIC-FEM).

• SEAFEM

is an advanced tool for analysing seakeeping problems. For further information, please visit SeaFEM.
