樁側與土側采用摩擦約束，樁底和土底采用tie約束，計算地應力時，第一步就不收斂，警告信息里全是

If significant clearance/overclosure exists between surface pair (assembly__t45_anpo-1-2_sn,assembly__t45_anpo-1-2_m) and the master surface does not have rotational degrees of freedom, adjustment is recommended for correct enforcement of the tie constraint

Slave surface assembly__t46_anpo-1-2_sn is a node-based surface used with surface to surface approach. In order to obtain improved stress accuracy with this approach, an element-based surface should be used instead.

麻煩各位指點一下該如何解決，不勝感激
