FEMLink 3.3

FEMLink provides bidirectional interfaces with a number of finite element codes. These are used to build FEM, post-process FE results and manage sets of frequency domain measurements.

Currently FEMLink cannot be run independently from SDT. You thus must be a SDT user to purchase FEMLink. The release rate for FEMLink is much faster than that for the base SDT and users submitting cases where the interface fails, typically get patches within a few days if not hours.
The latest patch is available at http://www.sdtools.com/distrib/femlinkpatch_dis.p. It contains compatibility enhancements for ANSYS, performance enhancements for NASTRAN and extensions of the ABAQUS reading capabilities.

Software What is supported

Ansys ans2sdt Reads binary .rst and .emat files for :
model definition (nodes, elements), element matrices (for use with upcom), and finite element results.
Reads and writes text .cdb files for model input (nodes, elements, materials, boundary conditions, ...)

Abaqus abaqus Reads binary .fil files for : model definition (nodes, elements), element matrices (for use with upcom), and finite element results.
Reads and writes text .inp files for model input (nodes, elements, materials, boundary conditions, ...)

Nastran nasread and naswrite
Read/write BULK files : FE model, boundary conditions, constrains, materials, physical properties)
Read binary OUTPUT2 files : FE model, full and element matrices, displacements, stresses, ...)
out-of-core element matrix manipulations
Read and write binary OUTPUT4 files.
Drive NASTRAN from Matlab.

Ideas

Universal Files : experimental and FE datasets.
Specific datasets supported FEMLink :
772, 788, 789, 2437 : Physical Properties (MASS, SHELL, BEAM, SPRING)
773 : Material Properties
780, 2412 : Elements (beams, 2D and 3D elements, shells, springs, rigids ans bars)
2414 : Analysis data
2432 : Permanent Groups

Samcef samcef
reads binary .u18 for models .u11 and .u12 for element matrices.

Read and write .dat (samcef input file)

Permas perm2sdt, reads PERMAS (> 7.0) files : for FE model and deformations.

Optimized handling of large files (> 2 GB) is implemented for NASTRAN, ANSYS and ABAQUS.
