It is not possible to calculate the example you created, due to an error in finite element analysis (analysis: Singularity)

Thank you for your enquiry and pe file. The model is not able to run the CBFEM as it is not possible to achieve equilibrium with a single anchor hence the notification message . For example you can see this if you add a 2nd anchor at plus 50mm and move your original -50 to have a 100mm spacing and the model with run your analysis.
