在SMP版本的LS-DYNA中提交了設(shè)有*CONTROL_ADAPTIVE關(guān)鍵字的模型,與沒有設(shè)置*CONTROL_ADAPTIVE關(guān)鍵字的模型相比,結(jié)果沒有變化。 預(yù)期模型應(yīng)該發(fā)生以下變化:單元隨著變形的增大,自動分裂加密,如下圖所示。實際后處理時發(fā)現(xiàn),單元沒有分裂加密。不知道這是什么原因呢?




用abaqus做umeshmotion磨損仿真出錯,剛開始就發(fā)生錯誤,錯誤如下54 elements in the adaptive mesh domain are distorting so much that they turn inside out.


1 elements in the adaptive mesh domain are distorting so much that they turn inside out. The elements have been identified in element set WarnElemAdaptMeshDistortStep3Inc69.
