Using composite shells in Open Radios

Fatmac

I'm really enjoying playing around with the OR solver. One aspect (among several others I'm afraid!) that I have not got to grips with is using composite shells. If any one can point me in the right direction here I'd be very pleased. I think it will required some form of custom model definition to change the shell property definition to some form of composite shell definition like /PROP/TYPE9 (SH_ORTH). When i try and run the attached file i get the following error
ERROR ID : 1052
** ERROR IN PROPERTY SET
DESCRIPTION :
-- PROPERTY ID: 1
-- PROPERTY TITLE: Default shell
-- MATERIAL ID: 1
ISOTROPIC SHELL USING ORTHOTROPIC LAW

ERROR ID : 3047
** ERROR IN MATERIAL/PROPERTY COMPATIBILITY

I think you forgot to attach the file. Not that I have yet tried used composite shells in Radioss, so I don't know if I can locate the error, but it will be easier to help if the file is attached.

I don't think there's a convenient way to change the /PROP/SHELL to /PROP/SH_ORTH other than re-entering all the elements and linking them to the new /PROP with a new /PART keyword.

Thank you for getting back on this -and yes I did miss attaching the simple file, I've tired to this time. What I was hoping is that I could use the ID generated in the input file are redefine it in some sort of custom model definition input.
In the input file generated for this simple example I see the following lines of text - I was hoping to some how use this block and redefine as a SH_ORTH

/PART/1
Default shell
1 1
/PROP/SHELL/1
Default shell
24 2 2

5 0.007 1 1
/SHELL/1
1 9 21 25 11
2 21 6 23 25
3 25 23 3 24
4 11 25 24 7
5 8 10 14 13
6 10
