各位行家，在abaqus提交計(jì)算之后出現(xiàn)了下述的warnings，有一些不是很理解，希望大神能夠指點(diǎn)一下，謝謝！

問題1：warning如下，想問一下這是不是提示我需要把接觸的主從面調(diào)換一下？

Please make sure that the mesh density of the slave surface in the contact pair (assembly_cobm18_block,assembly_block_combm18) is finer than the master surface. The analysis may run slower, may yield inaccurate results, and may require more memory if this is not the case.

問題2：warning如下，但不理解是什么意思？

The ratio of the maximum incremental adjustment to the average characteristic length is 1.11808e-02 at node 104206 instance part-1-1 on the surface pair (assembly_cobm24_block,assembly_block_combm24).

問題3：warning如下，根據(jù)字面意思的理解是有62個(gè)節(jié)點(diǎn)被調(diào)整超過一次，就有可能導(dǎo)致這些節(jié)點(diǎn)不在主面上。這62個(gè)節(jié)點(diǎn)所在的一對接觸面我是既設(shè)了容差又設(shè)了過盈量，會(huì)不會(huì)是這個(gè)原因？

62 nodes have been adjusted more than once. The subsequent adjustments may cause these nodes not to lie on their master surface. The nodes have been identified in node set WarnNodeAdjust.
