Hello, 

I am trying to prepare a mesh in ansys for a acoustic simulation. 

What I have is a CAD model of the body made with AutoCAD. the model consists out of the front and back plate (surfaces), the side wood panel (surface), the soundpost (solid), bassbar (solid) and the violin bridge (solid). I export the CAD model as .sat file, and start a structural mechanical analysis in ANSYS (student version) with the file as an import. What I am unsure now is how to connect those parts correctly. I left little gaps between the individual parts because I learnt that I can define the contact types in ANSYS for specific gap sizes. How would I do this properly to have a "glue like" contact definition? And also how would this work for the surfaces that I gave a thickness in ANSYS? How do I know in wich direction they gain the thickness so they dont overlap with the neighbouring surface? I am planning to only create the mesh in ANSYS export it as RST or CDB and then do the simulation with Actran (I could probably get some guidance for Actran at my university by my professor but not for Ansys). I also uploaded a picture in case it helps to show what I mean.

Hi

 

See our courses on contacts in order to bond and connect them.

All the best

Hello,

thanks a lot for your help!

I was following the course and was able to create a mesh with connected surfaces (by using shared topology)

Unfortunately I still have the problem of exporting the mesh itself from ansys mechanical. How can I do that? I have read that I have to create a solution for that? (I was planning to do the ssimulation in actran) I just need the mesh file as CDB but can not find anything like "export mesh as filetype" in mechanical.

Best regards
