SOLVIA Element Library
The following element types can be used in SOLVIA:
An axial tension/compression element with 2, 3 or 4 nodes, which can also be used as a cable element. In axisymmetric analysis it can be used as a ring element with 1 node.
A 2-D continuum element with 3-9 variable number of nodes for plane strain, plane stress and axisymmetric analysis. The plane stress element can also be used in 3-D as a curved or flat membrane element.
A 3-D continuum element with 4-27 variable number of nodes.
A 2-node beam element which can be defined with rebars and with the following cross-section options:
- Standard section beam of rectangular, pipe, circular solid, box, I, U or T cross-section;
- General section beam defined by moments of inertia and area properties;
- User section beam where the external and internal section boundaries are decribed using straight and circular line segments and the section properties including shear center location and the warping constant are calculated;
- Resultant section beam defined by moment-curvature and force-displacement curves;
- Integrated section beam with elastic-plastic material and evaluated by numerical integration.
The Standard, General, User and Resultant section beam element have a co-rotational formulation and can be used effectively also in large displacement analysis where the rotations are very large.
An isoparametric beam element with 2, 3 or 4 nodes and with rectangular cross-section. It can be defined with rebars.
An isoparametric pipe element with 2, 3 or 4 nodes and with optional ovalization modes. The centroidal axis can be a straight line or a circular bend. The pipe section can be defined with rebars.
A 3 node triangular plate element of the DKT type (Discrete Kirchhoff Theory).
A flat or curved shell element with 3-32 number of nodes and with variable thickness. The 4-node quadrilateral element and the 16-node cubic element are most often used. Rebar layers oriented in different in-plane directions can be modelled.
A translational or rotational spring connecting 2 nodes. The spring stiffness can be nonlinear by specifying the force-displacement or the moment-rotation curves.
A general mass/stiffness/damping linear element based on user-defined matrices.
A plane or axisymmetric (acoustic) fluid element using 3-9 nodes. The fluid element can be used for static and dynamic fluid-structure interaction analysis.
A 3-D (acoustic) fluid element using 4-27 nodes. The fluid element can be used for static and dynamic fluid-structure interaction analysis.
The FILM element is nonlinear and is formulated with interpolation of oil film pressure and temperature using the film thickness in the deformed configuration. The oil viscosity is temperature and pressure dependent and the generated heat is transported by in-plane convection and in-plane and out-of-plane conduction. See Oil Film Applications (PDF).
