Kampmann GmbH is an internationally leading specialist for heating, cooling, air-conditioning and integrated building automation. Within their virtual development process they are using the Altair HyperWorks® software suite, in particular AcuSolve®, the CFD solver; OptiStruct®, the suite's FE-solver and an optimization tool; and HyperMesh® for modeling and meshing tasks. For plant control design, Kampmann is currently considering solidThinking Activate®, a mapping software for control systems. Thanks to simulation, Kampmann engineers are now able to answer questions regarding the internal processes of the system, which are difficult, if not impossible, to study through physical testing.
