why Rigid body attributes also need solid section?

lch4302

rt
*SOLID SECTION, ELSET=Reservoir tube, MATERIAL=Elastic_steel
*SOLID SECTION, ELSET=Cylinder tube, MATERIAL=Elastic_steel
*SOLID SECTION, ELSET=Oil_Seal, MATERIAL=Elastic_steel
*SOLID SECTION, ELSET=Base_Cup, MATERIAL=Elastic_steel
*SOLID SECTION, ELSET=Rod_Guide, MATERIAL=Elastic_steel
*SOLID SECTION, ELSET=Base_Valve, MATERIAL=Elastic_steel
*RIGID BODY, REF NODE =     190003, ELSET = Rod_Guide
*RIGID BODY, REF NODE =     190002, ELSET = Base_Valve


if not，error will arise like below，why?

"Error in job 22271376_HM: ELEMENT SET BASE_VALVE REQUIRES A *SOLID SECTION PROPERTY DEFINITION IN ADDITION TO THE *RIGID BODY PROPERTY DEFINITION"

Many thanks!

英文回复还是中文回复呢，
用的刚体约束，建立的部件还是可变形体，可变形体就是要定义材料数学，属于abaqus强制的，按照规矩办事嘛。

Thanks for your reply!
Do you know how to realize it in hypermesh?
As you know,
the key words "rigid body" and "solid section" are both property setting in hypermesh.
so it is forbiden to apply two propery for one component.
So my question is how to solve it in hypermesh?

hm的话我用的不熟悉，很抱歉

hypermesh绘图区下方菜单栏properties——create——输入name——type 选择rigid section——card image选择rigid body——材料不用选——create/edit——选择参考点和单元集——return——点选assign——选择单元赋予属性即可
