I used ansys 2023R2 version to learn how to calculate NVH. There some issues are as follow:<\/div>\n
1. I finished all setup when I compared the force calculation between moving1.Torque and MST_Torque, before starting to analyse, it can setup Airgap_arc (Angle is 45deg) as an edge. However, the software said “TAU: Surface Mesh Generation Failed.” after I setup MST_Torque by fields calculator;<\/div>\n
2. It cannot setup Arigap_arc as edge of MST_Torque by fields calculator after finish all calculations because the button is disappear;<\/div>\n
3. The result of MST_Torque is wrong if the Airgap_arc cannot be setted as edge;<\/div>\n
4.There are some definitions that do not illustrate it, like SymmetryFactor. It cannot set the expressions in the field calculator if I don’t get some definitions like these, which would affect my calculation result with other projects;<\/div>\n
4. The document (Maxwell NVH, Workshop 1:NVH Analysis Setup in Maxwell 2D) shows the result is 6% difference between Moving1.Torque and MST_Torque (fields calculation), but my result are only 6% and less 50% of the Moving1.Torque, which means fields calculation is 0.27Nm (2023R1), 2.1Nm (2023R2), but the Moving1.Torque is 4.3Nm.\"\"\"\"\"mesh\"\"\"\"\"\"\"\"\"\"<\/div>\n
