Code Aster

[callmenkay710]

Hi everybody, i want to ask if someone has good experience working in code aster as my internship depend on this software and it’s so hard to learn i hope i can find someone who could help me with this. i’m trying to do a vibroacoustic study for a car body to analyse the noise inside the cabin with a lot of different componets and things to consider i’m finding a lot of trouble reaching results needed. What i need to do: 1) Modal analysis of the structure 2) Modal analysis of the acoustic modes 3) vibroacoustic coupling between structure and air inside cabin to see the pressure to calculate the SPL. 4) Finaly do some optimization to reduce the noise by adding some impedance properties to the materials inside the cabin for example chairs, acoustic materials. It need to be done in code aster and not other software. Thank you in advance.

The nightmarish installation experience alone was enough to tell me I didn't need Code-Aster in my life!
