Efficient exhaust pipe model creation [Mesh modeling man-hours reduced by 70%]

A certain automobile manufacturer has been working on improving the vehicle development process by drastically reducing the CAE man-hours in order to handle many car variations (exhaust pipe variations). Among them, the man-hours for creating a mesh model could be reduced by 70% by replacing the conventional software with Jupiter.

background

More than half of the exhaust system CAE man-hours are mesh model creation man-hours.

In the conventional vehicle development process, CAE man-hours are enormous, and especially mesh model man-hours account for more than 50% of the total. Specifically, it took time for each welded part, which is an evaluation part, meshing of bent pipes, modeling of mufflers without CAD, and bracket welded parts.

Solution

Development of mesh modeling function for exhaust system with Jupiter.

Therefore, with Jupiter, we have developed our own mesh modeling functions for exhaust systems, such as pipe mesh, remesh for evaluation departments, various solid welding, and muffler modeling. At this time, the problems were thoroughly identified, and after 1.5 years of development and testing, the replacement of the conventional software with Jupiter was completed.

effect

70% reduction in mesh modeling man-hours and smarter development process.

By switching from the conventional software and operating it in practice, we were able to reduce the mesh modeling man-hours and total man-hours by 70%. This enables front loading that can utilize CAE from the drawing stage, and enables diligent feedback and smart overall development.

Jupiter-Exhaust Modeling

Jupiter-Exhaust Modeling is a CAE modeling software for exhaust systems that enables fully automatic meshing of exhaust pipes. In recent years, due to the tightening of exhaust gas regulations, the demand for design examination by CAE is increasing. However, since the exhaust system is a downstream process, it is necessary to consider it in a short time. This software reduces man-hours by automating and standardizing modeling operations using general-purpose functions that correspond to the specifications of each company.

Pre-Post

Jupiter-Pre

Jupiter-Pre has many pre-functions for finite element method (FEM) analysis, which are characterized by large-scale support, high customizability, and high-speed automatic meshing, which are strong against large-scale models with more than 100 million nodes and large man-hour reduction by automation. It is a general-purpose CAE software equipped. One software on Windows platform enables all CAE preprocessing, from CAD import to solver input file and export the results. It supports almost all kind of CAE models for simple shape linear analysis, nonlinear large-scale analysis, and multiphysics analysis. You can also utilize "unlimited" Undo/Redo operations. In addition, the model tree works with CAD and FEM, allowing you to move CAD shapes and FEM meshes in both directions. Therefore, you can operate with a flexible flow instead of one-way traffic. Jupier-Pre has been developed since 2002. We will provide thorough supports and unique customization to the developer.
