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. WitrynaSet this parameter equal to the name of the alternate input file containing the imperfection data, in general, as the node number and imperfection values in the global coordinate system. See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis User's Manual, for the syntax of such file names.
