Your model is not constrained properly, your first six modes are zero, then you have rigid body movements. Also check your total mass of the model, the units of Density in Ton/mm3, EX in MPa and length in mm are correct, the the output mass will be in Tons. Check your F06 file to see is the resulting computed mass is in line with the mass of your model.
we have checked our constraints.Yes it is ppt30 ( Plastics material ). Two parts are connected with rigid elements,& model has been applied with four constraints. Is there any other way to connected two parts ( If it is actually connected by adhesive like silica material )?
We checked & found duplicate node,now these nodes get merged ( Now see the attached results ).
plz Check the mass properties of the model, & suggest...
