Femtet at a Glance

Femtet is all-in-one CAE software equipped with 3D solid modeler, pre-/post-processors and 8 types of solvers.
Tutorials and examples too are available. Here is a brief look at each functionality.

Modeling / Results Display

Modeling(CAD)

Femtet allows intuitive operations of modeling without knowing complicated commands in depth. Import and export of CAD data are supported.

Meshing

Triangle or tetrahedral meshes are automatically generated by simply pressing a button. Partial mesh size setting and adaptive meshing are supported as well. Mesh size suitable for individual analysis is set automatically. Femtet can import mesh data in Nastran format for analysis.

Results Display

Simulation results are displayed in various ways like contour diagram, deformation diagram, vector diagram, cross-sectional diagram, and animation. The results can be saved in csv format.
