Drastic Difference in Static vs. Riks analysis

Drastic Difference in Static vs. Riks analysis

Hi All

in the files attached you see the results for the static and Riks analysis for a loading in the z direction =100 N , that have a drastic difference , I will have to do a buckling analysis on this model , but first for another reason I need to know that reaction results in different load cases , but for the analysis , for example for tension i tried both static general and Riks method , but the results have too much difference , as the riks stresses are so much higher than the static one , while I also don,t know that whether i should expect nonlinear behavior for this geometry , while the parts are orthotopic materil , the first one is the risk analysis with a 50 MPa result for a 100 N loading

i appreciate your attetion
