abaqus求解大变形采用地是拉日法还是欧拉法？

还是可以采用ALE法
还是都可以采用？
abaqus可以采用无网格法吗？

Abaqus mostly use lagrangian type. I've never seen any pure Eulerian type. It apply ALE in adaptive mesh in explicit solver. I haven't seen any built in meshless method in abaqus, but I believe by using UEL, there are no problem to do it.

The alternative to a “small-displacement” analysis in Abaqus is to include large-displacement effects. In this case most elements are formulated in the current configuration using current nodal positions. 上面一段话摘自: abaqus manual 里的，应该说明ABAQUS是使用的 updated lagrange方法。

Explicit CEL used pure Eulerian analysis.
