4. W ONE CAN I DO THAT A Yes All the Simulink code in Thermolib is visible for users and can be modified as they see fit Only the code for the basic building blocks Thermodynamic States and Properties is not visible and cannot be modified The Simulink code constitutes a large part of the Thermolib library and is generally a good starting point to modify and create new blocks Q Is IT POSSIBLE TO VIEW MODIFY THERMOLIB SOURCE CODE A Yes and no Please see the answer for the question I would like to modify a Thermolib component or create a new one Can do that Q WHAT ARE THE RECOMMENDED SOLVER SETTING FOR THERMOLIB IN SIMULINK A There is no general solver setting recommendation for Thermolib models as it strongly depends on the problem EUtech Scientific Engineering GmbH DennewartstraBe 25 27 52068 Aachen Germany _http www eutech scientific de Tel 49 0 241 963 23 80 Fax 49 0 241 963 23 89 WE EUtech EE Scientific A Engineering 6 TROUBLESHOOTING Q GET A CERTIFIED TIME ERROR LICENSE ERROR WHEN TRY TO RUN THERMOLIB WHAT CAN IDO A These are the steps to update a certified time on a CodeMeter USB stick e g for Thermolib licenses 1 Open the CodeMeter Control Center from your taskbar by double clicking on the CodeMeter icon 2 Start the WebAdmin interface from the CodeMeter Control Center by clicking on the button WebAdmin 3 Now your web browser should open and you can navigate
