Femap Version 10
2D Mesher
Improved meshing on curved nonplanar surfaces
 Mesh algorithms have been
improved, and the meshers have
been expanded to automatically
apply multiple mesh approaches
resulting in the best possible
mesh without user intervention
 Mesh options are saved for easy
re-meshing

Femap Version 10
3D Solid and Surface Meshers
 Internal and branching faces
and curves are accounted for
within a solid
 Create a consistent mesh in
volumes containing 3D, 2D,
and 1D entities
Example:
 Reinforced concrete model:
steel beam elements with
concrete tetra elements in a
matched mesh

Improved Geometry Handling – Shells
 Create contiguous meshes through
complex geometry intersections
 Non-manifold geometry – instances where
three or more surfaces share the same
curve, e.g. T-junctions
 Mesh will connect and match on all
surfaces
 Previously a limitation in Parasolid

23
Femap Version 10
Improved Geometry Handling – Shells and Solids
 Combine surface geometry and solid
geometry making it easier to join solid
and shell meshed components together
 Internal faces have edges that are Tjunctions
 Tetra Mesher now handles internal
triangles or quads, and creates a
combined shell / solid mesh with slight
embed for moment transfer.
