How do you create a concrete filled steel tube in ABAQUS?

WitrynaYou must request results (.fil) file output for the nodal displacements so that you can use the buckling analysis results to seed the ABAQUS/Explicit mesh with imperfections. In addition, request preselected field variable output to the output database (.odb) file and prevent unnecessary results from being printed in the data (.dat) file. Witryna1.使用 *IMPERFECTION 关键字为后屈曲和坍塌分析引入几何缺陷。 2.几何缺陷可以基于前期计算过程中写入到输出数据库（.odb）文件或结果（.fil）文件的节点位移。 1) FILE 参数用于从先前的计算中定义结果文件的名称。文件扩展名是可选的；但是，如果结果文件和输出数据库文件都存在，默认使用结果文件。 2)必须使用STEP参数来识别先前 … green fodder crossword clue
