有無(wú)大佬知道LS-DYNA的約束部分關(guān)于*CONSTRAINED_RIGID_BODY_STOPPERS中關(guān)于PSIDMX和PSIDMN這兩個(gè)關(guān)鍵字的使用，我參考手冊(cè)建模，設(shè)計(jì)好參數(shù)，計(jì)算結(jié)果這兩個(gè)功能并沒(méi)有顯示出預(yù)期的效果，不知道是不是參數(shù)設(shè)置的問(wèn)題，反復(fù)檢查也沒(méi)檢查出來(lái)，求大佬解答

ERROR: Abaqus/Explicit requires isothermal rigid bodies to have a non-zero capacitance unless temperature degrees of freedom are constrained with the *BOUNDARY option.

報(bào)錯(cuò)： The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRot1Axis have atleast one axis about which the rotary inertia magnitude is zero, and the rigid bodies have atleast one

我用LS-Prepost作為前后處理，設(shè)計(jì)了如下兩個(gè)小球相撞的場(chǎng)景：施加了Z方向重力場(chǎng)（LOAD_BODY_Z），小球通過(guò)鋼索吊起，鋼索（梁?jiǎn)卧┖托∏颍▽?shí)體單元）通過(guò)CONSTRAINED_RIGID_BODIES連接。一個(gè)小球傾斜一定角度，在重力和初速度（INITIAL_VELOCITY_NODE）下撞向另一個(gè)小球，鉸接方式用了CONSTRAINED_JOINT_REVOLUTE。

BOUNDARY CONDITIONS ON RIGID ELEMENT NODES SERVE ONLY TO DEFINE SYMMETRY FOR CONTACT SURFACES (NODE 682 INSTANCE TOOL-1). THE REFERENCE NODE SHOULD BE USED TO CONSTRAIN RIGID BODIES。
