热传递分析时报接触面的错误
做热分析的时候，遇到下面的错误。哪位大侠清楚，给指点一下，谢谢啦！*** ERROR #934 ***
Invalid CGAPG element 114722
GA is within the solid element 21281 without explicit specification of the
contact face. This makes it possible that the face nearest to GA is interior to
the solid model rather than on the outside surface. Please specify the contact
face explicitly or create 2D elements (skin) on the body surface as the
contact obstacle. 哪个做过的，分享一下吧，谢谢。
