-
- RSSCON1 bulk card added to define connection between shell and solid elements.
- RSSCON1 is mapped to group entity.
- SENSOR input to activate loads
-
- New bulk cards SENSOR to define sensor input.
- SENSRAD bulk card to defined union of several sensor inputs.
- Subcase references of SENSOR and SENSRAD are defined through SENSOR in subcase information entry.
- Modal damping as a tabular function of mode index
-
- New bulk card TABDMP2 to define modal damping as a tabular function.
