Hi there,I’ve got a problem during using the optimization module in abaqus.
I use the utractload subroutine during static analyzing successfully, while when I want to topology optimize the same model using the optimiztion module and submit the optimization job, an error will come out, says ‘USER SUBROUTINE UTRACLOAD IS MISSING’.
I've maked sure that it's not the problem about the program. Because when I don't use the subroutine, the optimiztion job will run succesfully. I think the key to the question is how to add a subroutine into the optimization job.But I don't know how.There is no box to insert the subroutine file and even no hint for asking for the subroutine, it just gives the error out. I’ve searched and thought about how to solve it for a long time, but I still can’t find out the way. I've already checked the .inp file, while there is no way to add subroutine in it for me. I also tried to find out how the Tosca which controls the optimization module combined in Abaqus works and change some .bat files. But it still not work. Help me, plz.Thank u anyway for reading.
