FEMLink

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.

FEMLink is designed to pre- and post process industrial size models. It is thus systematically optimized to handle large files (result data > 2 GB and model data with several hundred thousand nodes or elements).
By nature, translators such as FEMLink are imperfect. SDTools thus makes a permanent effort to improve FEMLink by taking into account files submitted by users. Users submitting cases where the interface fails, typically get patches within a few days if not hours.
For the latest patch contact support at info@sdtools.com.
Currently FEMLink cannot be run independently from SDT, you thus must be a SDT user to purchase FEMLink.
