Analyze the cooling of the e-axle with Simerics, which has strong rotation and VOF capabilities! It's also suitable for switching from other general-purpose CFD solvers or particle methods.
【The following fluid analyses are possible】 ■ Free surface flow ■ Flow considering the compressibility of air contained in liquids ■ Pressure pulsations, water hammer effects ■ Coupling of pump flow with the rigid body motion of valves and cam rings ■ Flow in low to medium vacuum conditions ■ Compressible flow (subsonic) ■ Cavitation ■ Flow field (velocity vectors, pressure), flow rate, fluid forces, and time variations of torque Recently, there has been an increase in projects for cooling analysis of e-axles for automobiles, and when solving the VOF method with other CFD software, we have received inquiries such as: - Analysis time is too long - It is difficult to create fine computational meshes - The solution diverges and does not converge Additionally, even when analyzing with particle methods, we have received feedback that accurate thermal analysis cannot be performed, and it is only possible to identify areas where oil is present. Our company has gained know-how that cannot be obtained solely from software sales by undertaking actual contract work from Tier 1 customers.

basic information
(1) Automatic generation of calculation meshes! Even for complex flow paths, automatic generation of calculation meshes is possible with simple button operations. Additionally, for pump chambers that involve rotation/volume changes, high-precision calculation meshes can be automatically generated using a dedicated mesh creation module. It is possible to automatically execute the movement/rotation/deformation of high-precision meshes without tedious tasks. (2) Fluid analysis of various gear pumps is possible! Simerics MP+ has mesh creation capabilities for various pumps, starting with gear pumps, making it easy to perform calculations for different pumps. It also has mesh creation functionality for valves, allowing for calculations of flow paths that include valves, and coupled analysis is also possible. (3) More accurate modeling of aeration/cavitation! It includes a high-precision cavitation model, enabling the prediction of non-condensable gas expansion and steam generation due to cavitation. (4) Calculation of free surface flow It is now possible to analyze oil scooping within gearboxes and oil suction from oil pans during pump startup.

Applications/Examples of results
Simerics MP+ is primarily used by automobile manufacturers and automotive-related parts manufacturers in Japan, with numerous achievements in oil pumps used in automotive ATs and CVTs, as well as engine oil pumps. Additionally, it has a wide range of implementation achievements not only in the automotive industry but also globally. Examples of achievements worldwide by the developer can be found at: http://www.simerics.com/testimonials/ There are many cases where companies, both overseas and domestically, that have already purchased multiple fluid analysis software, have chosen to buy it for its user-friendliness, improved accuracy, and reduced calculation time in the analysis of volumetric pumps such as gear pumps and vane pumps.
