The new FE Toolbox from Lauterbach Verfahrenstechnik GmbH combines precision and user-friendliness in one application. Our tool is tailor-made to reliably achieve a fast and accurate design of various components in pressure vessel design and plant design. With COMSOL Multiphysics we have a strong partner in the field of finite element methods. COMSOL Multiphysics offers the possibility to develop precisely tuned applications to make complex calculations accessible to a wide range of users. We have applied our expertise in the field of finite element calculation and our know-how from 30 years of engineering practice in apparatus construction and developed a new unique application that delivers valid results in the shortest possible time and does not require any knowledge in the field of FEM. Everything from a single source • CAD model creation • Setting up the simulation environment • Meshing to the finite element model • Solution and presentation of results • Evaluation of results according to DIN EN 13445, AD 2000 or ASME VIII • Presentation of the results with powerful rendering After entering your boundary conditions in the revised LV-Soft interface, such as material parameters (material server integrated in LV-Soft) and geometry data, you start the application via a button in the LV module. After a successful calculation run, all relevant results are automatically entered in the LV-Soft interface, and you can directly see whether your component is sufficiently dimensioned. If you now want to change input data and have them recalculated, you only must change your values accordingly in the LV-Soft interface and trigger the new calculation via "Calculate" in the application. All data is read in again and the calculation is carried out. Being able to correctly interpret and categorize the results of an FE calculation requires a lot of experience from the user in this field. Which quantities are relevant? How are different areas categorized and evaluated accordingly? What needs to be considered when equivalent stress values are too high? Modern regulations such as AD 2000, DIN EN 13445 or ASME VIII specify how a component is to be classified and categorized. A distinction must be made between general and local areas. But when is an area to be classified as local or general? With our new tool, these questions are already clarified for you. We evaluate all results according to their type of origin and locality and compare all relevant variables with the permissible values. For you, one look at the results table is enough to know if the component is sufficiently dimensioned. FE analysis can be that simple.
