发现不了元素的报错问题？

接触设置有问题，找不到master segment，重新设置接触，SSTYP和MSTYP选1、2或3，视情况而定

SSTYP:=Slave segment set or node set type. The type must correlate with the number specified for SSID:

EQ.0: segment set ID for surface to surface contact,

EQ.1: shell element set ID for surface to surface contact,

EQ.2: part set ID,

EQ.3: part ID,

建议再检查下接触，或确认单元是否赋予了属性。
