Hi There,
I am Simulation an AirBag with MONVOL_GAS option with CardImage PresLoadCurve Option with material Rubber and Foam.
At the start a huge ERR% is occurring (-99%). Later some elements are undergone small strain formation with
such message:
** WARNING ZERO OR NEGATIVE SUB-VOLUME : 3D-ELEMENT ID : 41274
ELEMENT IS SWITCHED TO SMALL STRAIN OPTION
Later there is a huge drop in time step ( in order of 3.0484E-67) with zero energy error and gradually time step increased and fixed at 1.1377E-06 and simulation running smoothly.
But in animation file the volume of AirBed becomes Zero with gradual increase in pressure.
Prop used:
P14Solid
ISOLID: 14 (with 12 run automatically killed due to exceeding energy error limit)
Ismstr: 0 (used 2 with DT/BRICK/CST but same effect)
Icpre: 1
Please suggest some modifications.
I would like to share model file through Secure File DropBox if needed.
