OOFELIE::Multiphysics link to ZemaxOpticStudio

The OOFELIE::Multiphysics Solver is tightly combined with ZemaxOpticStudio through automated in-memory data exchange to help engineers accurately predict the behavior of optomechanical systems and MOEMS.

Presentation of the link

In a variety of optical applications, optical designs have to be combined with thermo-mechanical matters. For this reason, the OOFELIE::Multiphysics Solver automatically links to the well-known optical design software ZemaxOpticStudio.

While combining data from finite element analyses with ray-tracing tools typically requests time-consuming human operations, the automated in-memory data exchanges between OOFELIE::Multiphysics and ZemaxOpticStudio will guarantee you a fast, easy-to-use and reliable design flow.
Beyond the so-called “STOP” (Structural Thermal Optical Performance) analyses, this integrated solution also offers advanced modeling capabilities for the design of complex electro-optic devices such as MOEMS, including their steering mechanisms and active/adaptive optics.


To interact with the optical design software ZEMAXOpticStudio, OOFELIE::Multiphysics was provided with the following capabilities:

  • Automated in-memory data exchanges with ZEMAXOpticStudio
  • Easy optical CAD export from ZEMAXOpticStudio to OOFELIE::UI for further modeling
  • Irradiance exchange to calculate power dissipation in the components
  • Expression of structural deformations exchanged with ZEMAXOpticStudio as:
    • A linear combination of Zernike polynomials
    • As grid of points
  • Separation of the rigid body component
  • Automated modification of the optical problem
  • Automated retrieval of optical performance indicators
