 +With the help of this tool, the possible layups can be determined for the given system and load situation. The optimization can be restricted with regard to producers, number of layers or by means of limits for the panel thickness. Furthermore,​ outer cross layers or double layers can be included or excluded. With the option "​Vibration verification according to EN" the base document is included in the vibration check or not.

 +With the buttons "​Start"​ and "​Stop"​ the calculation is controlled. Please be patient, depending on the selected parameter the calculation may take a little longer.
