Address & Contact Information
Polytech A/S is a Danish subsupplier to the wind industry, providing lightning protection solutions and other add-ons to wind turbines and wind turbine blades. These solutions are developed from the very early stage of a project using advanced engineering and simulations. Following a model verification using numerical tools, material engineering, prototyping, and full-scale testing is conducted. Here, we utilize our materials lab and one of the largest commercially available lightning laboratories to satisfy customer expectations on serial delivery all around the globe.
The combination of advanced engineering and modeling, prototyping, and verification testing is helping industries develop components that last longer and offer greater protection. Our proposed solutions are designed to comply with the most up-to-date industry standards, along with ensuring a short time to market for our customers.
COMSOL Multiphysics® Competencies
The engineers at Polytech A/S are experienced with COMSOL Multiphysics®, having used the software for more than 20 years. This knowledge allows us to simulate: magnetic and electric fields, the current distribution within complex materials and structures, inductances and capacitances related to high-voltage engineering and lightning protection, and the prediction of lightning attachment points and lightning parameter distributions for complex structures. Stray current mitigation using sacrificial anodes and the cathodic protection of diverse metallic structures have also been solved with COMSOL Multiphysics®. Multiphysics problems involving electrical and thermal phenomena as well as fluid flow have been solved over the years as well.
The engineers and physicists at Polytech A/S help solve complex problems, applying a natural approach to understanding the physics, explaining the means for solving the problem to customers, and reporting and documenting the solution thoroughly.
