**Case Overview** ■Product Name: Femap Thermal, Femap Flow ■Analysis: Thermal Fluid Analysis ■Industry: Automotive Femap Thermal/Flow is software for thermal fluid analysis that operates as a Femap application. It can be used with the same operational feel as Femap. By combining Femap Thermal and Femap Flow for thermal fluid analysis, we calculated the flow of exhaust gases within the muffler and the temperature distribution of the muffler due to high-temperature exhaust. Using Femap Thermal and Femap Flow simultaneously allows for thermal fluid analysis. It can solve complex problems such as heat transfer at the fluid-structure interface, fluid flow, thermal conduction in structures, and consideration of radiation at the surface of structures. In this case, we conducted thermal fluid analysis focused on the muffler. We confirmed that we could obtain the temperature difference of exhaust gases at the inlet and outlet, the flow of exhaust gases within the muffler, and the temperature of the surface of the muffler structure, providing the parameters necessary for design. □ For other features and details, please refer to the catalog.

Femap Flow is a fluid analysis solver that is used as an add-on to Femap. Customers who are currently using Femap and wish to conduct fluid analysis can do so by adding it to their existing Femap environment, allowing them to perform fluid analysis using the Femap GUI. 【Features】 Not only can fluid analysis be performed, but by using the Femap GUI and model files, structural-fluid coupled analysis with NX Nastran can also be easily conducted. Additionally, by adding the Femap add-on thermal analysis software, Thermal, thermal-fluid coupled analysis can also be easily performed. 【Application Examples】 ○ Steady-state and unsteady fluid analysis are possible. ○ Analysis considering viscosity and compressibility is possible for liquid and gas layers at sonic speeds (up to Mach 4). ○ Modeling of Newtonian and non-Newtonian fluids is possible. ○ Turbulence models such as the FTV model, Mixing Length model, and k-ε model can be utilized. ○ Periodic boundary conditions can be modeled. ○ Fans can be defined not only at boundary surfaces but also in flow exposure. ◎ For more detailed information, please refer to the catalog or contact us directly.

If CAD data is not properly managed, it can take a long time to search for the desired CAD data. Even if the search time for each instance is short, when many people search multiple times, the total wasted time becomes enormous. Why is it not properly managed? The reasons are, as expected, either that management rules have not been established, there are problems with the management rules, or the management rules are not being followed. If there are no problems with the management rules but they are not being followed, we can only ask for compliance. If that is not the case, there may be issues with the management rules, including the possibility that they have not been established. One obstacle to establishing management rules is the resistance to changing the way work has been done until now. Everyone tends to be reluctant to change familiar methods. However, if the current way of working is an obstacle to properly managing CAD data, shouldn't we change the way we work? So, how should we change our work methods? The suggestion is to align the work methods with CAD data management software.
