    Status: Answered => Open

jacopo is still having a problem:
Hi. I think i did it. I used FEMAP, 3D software. I downloaded trial version. This software allow you To open file .nas Or .bdf, IT has a lot of format type. Then i export all The created mesh as stl file. Theoretically IT should merged al The vertices outomatically. I didn t open the the stl file yet.
-> Is in yade  a procedure that allow me to open IT? As The one with GTI surface?
-> At this point i only imported The geometry.... How about The material? I could read the value set in the original file bdf , But The two softwares  probably work with different material values. Do you think i should have To work only on contact? ... Becouse i could set in The beginning of The script the material But in this way i would define only one material for The whole aircraft. What do you suggest me To do?

Chareyre proposed the following answer:
Hi Jacopo, I'm affraid the only realistic comming to my mind beyond
decrypting it by yourself is to ask nastran people about conversion to a
more generic format.
