we have created load collectors and defined card image as Gravity where we provided g value as 9810 mm/sec^2 and direction in Y axis.

Also defined load steps.( through support 1= Gravity collector no) while solvning this we are getting the following error.

WARNING: GRAV SID 3 is not referenced by Case Control.

ERROR # 23 FROM SUBROUTINE renum2

SID 3 is referenced by SUPORT1, but is not referenced by any bulk data.

kindly provide your valuable suggestion for the same.

    Delete existing loadstep & recreate it and you should be all set.

    I think you are using HW9.0; in loadstep GRAV card needs to be referenced by load & Support 1 should be reference by SPC.

    We are using Hypeworks 9.0

    What are all the steps to be followed for load collector referencing? (in loadstep GRAV card needs to be referenced by load & Support 1 should be reference by SPC.)

    With regards and Thanks
