LMS Samcef Thermal

Solve complex thermal and thermomechanical problems including contact and radiation

LMS Samtech Samcef Thermal enables you to model thermal and thermomechanical problems affecting structures. The thermal solver models conduction and advection subjected to convection and radiation boundary conditions. The finite element library consists of many element types allowing anisotropic and multilayer composite properties.

You can apply the convection boundary conditions directly to the structure or via flow channels using correlation formulas. You can also apply thermal contact between dissimilar meshes as well as perform a view factor calculation using a raytracing algorithm. The surface radiation calculation includes wavelength dependent thermo-optical properties and the application of a solar flux, including shading.

In addition to basic thermal elements, fully coupled thermo-electromagnetic elements are available. This modeling is used to calculate heating of a structure (and possible degradation) while solving Maxwell equations.

All properties in LMS Samcef Thermal (material, boundary conditions and contact conditions) can be a function of temperature resulting in the creation of a nonlinear problem. The thermal solution shares parallel nonlinear solver technology with LMS Samcef Structure Nonlinear and LMS Samcef Amaryllis. This common platform is beneficial when performing a thermomechanical analysis. With a fully coupled approach, you can model heat generation by material deformation (plasticity) as well as friction. You can use LMS Samcef Amaryllis to study the thermal response of the heat shield of atmosphere re-entry vehicles or composite structures subjected to fire.
