The complexity of thermal processes is frequently underestimated. The modeling of such processes can accelerate the analyses, optimization and design procedures considerably. Dedicated models also provide practical understanding of the processes itself, as well as for example of the impact of variable process settings on product quality aspects. Solutherm has extensive experience in the development of calculation models, from Excel to Matlab. Each developed model is thereby characterized by a pragmatic and fit-for-purpose approach, without getting caught in avoidable complexities.
