小弟，新手一枚，做ABAQUS复合材料静力分析遇到如下问题

问题如下，小弟做碳纤维电池盒强度分析，材料是和层板，属性是实体，均质。网格我画的是四面体单元（C3D10: 十结点二次四面体单元）.，分析时一直存在下面问题，SHEAR MODULUS DEFINED BY ENGINEERING CONSTANTS MUST BE POSITIVE. FOR ZERO SHEAR MODULUS, USE A SMALL NUMBER GREATER THAN 1.00000E-36 ELEMENT 1 INSTANCE BATTERY_XIAOMOXING-2-1: LAYERED MATERIAL PROPERTIES CAN NOT BE SPECIFIED FOR THIS ELEMENT TYPE.
求大神帮忙答疑啊
