/DEF_SHELL
Block Format Keyword Used to set default values for certain parameters in all shell properties, but options could still be changed in each property set input and in this case, the latter will prevail.

Comments
- This card is read only once. Only the first card /DEF_SHELL written in the model is used. The other card /DEF_SHELL is ignored.
- Refer to the comments in /PROP/TYPE1 (SHELL) for more information about these input options.
- Flag Ioffset to
consider shell offset in the contact interface is compatible with the following
contact interfaces:
- /INTER/TYPE7
- /INTER/TYPE10
- /INTER/TYPE11
- /INTER/TYPE14
- /INTER/TYPE15
- /INTER/TYPE18
- /INTER/TYPE19
- /INTER/TYPE21
- /INTER/TYPE23
- /INTER/TYPE24
- /INTER/TYPE25
With Ioffset =1, shell offset is applied to all compatible contact interfaces defined in the model.
