Hi,

I am a student how write my master thesis. I will model various bridge typs using mostly SHELL181 elements. However, I want an efficient way of creating and adjusting geometries into the ANSYS MECHANICAL ENTERPRISE. My intial idea was to creat geometries in Spaceclaim, export as .anf file and then using /input, gemotry.anf. This doesn´t work unfortunally.

In previoud example file i got they wrote sometinhg like this, however I noticed there can be some problems when using .igs files and that it is better to use .anf or .inp files: 

! Wand 1

/AUX15                              

IGESIN, RhinoModell_W1, igs         ! Import Rhinomodell

/prep7                              

NUMMRG,ALL                          

asel,s,loc,z,-0.01,-100000  

asel,u,loc,Y,2,100000

aovlap,all

NUMCMP,area                        

allsel

If someone could show me how to do that it would be healpfull.
Thanks beforehand.

Hello Filip,

 

One thing you might consider is to locate the Help articles shown in the image below and try a number of different available options for importing geometry into MAPDL:

If you have an .anf file, I think all you need to do is to read it into MAPDL with the /input command:

/aux15

/input,filename,anf

 

The following Help article describes .anf file contents/format:

 

but I don't see the simple instructions regarding how to read it in. So I'm not 100% certain, but I suspect what I have above is correct.

Kind regards,

 

Bill
