ERROR # 4003: Abnormal termination in NLGEOM subcases

Hello, 

 

I am trying to run a topology optimization study on a model with non-linear geometry (large displacements). I am applying my loads by imposing a force via NLOAD1 Card Image. However, whenever I run the study, I receive the following error:

 

ERROR # 4003: Abnormal termination in NLGEOM subcases.

 

I have no idea what this error indicates, and I can not seem to find any other online resources to help me troubleshoot. 

 

The check screen output is shown below:

Additionally, here is my NLOAD1 definition:

And here is my Non-Linear subcase definition:

Please let me know if you can help me identify the source of this error.

 

 

Thanks in advance!
