I try to calculate the perfect shell without imperfections with non-linear geometry.
Finalize without errors for full time line.
If I draw graph force-reaction dependency of time, then error happen at the top.
average force= 0.023996 time avg. forc= 0.019977 largest residual force= 0.000198 in node 333 and dof 1 largest increment of disp= 8.813149e-05 largest correction to disp= 2.800649e-05 in node 247 and dof 2 divergence; the increment size is decreased to 2.574921e-07 the increment is reattempted *ERROR: increment size smaller than minimum best solution and residuals are in the frd file exit status 201
