Maybe this is an incompatibility like you say, since L-BFGS only uses the initial Jacobian and I never tried setting the scale type.<br>

First I tried shrinking by a factor 1000 but this converged very quickly with all test data I could provide, including the data which was problematic with the large grid. So I settled for a reduction in size by a factor 125. The grid size is 13,230. This is a decent test case because the solver fails to converge with the options I was using before, and it is small enough that I can run it with the options you suggested (-snes_fd_color -snes_type newtonls -snes_monitor -snes_linesearch_monitor -ksp_monitor -pc_type lu).<br>

There is an additional term in the Lagrangian which describes external forces which arise from various data sets, and that term contains nonlinearities (field terms higher than linear). The grid has about 1.6e6 elements, and the displacement field has 3 components at each grid element.<br>

In particular, the methods were successful for the infinitesimal bulk strain (compression) energy, as well as the full infinitesimal strain energy (bulk + shear), but I'm now trying to generalize to the finite strain, as certain data sets are known to result from displacement fields for which the infinitesimal strain is a poor approximation.<br>

For example, I am not allocating any matrix for the global Jacobian, and I believe this prevents me from changing the line search. If I'm mistaken I would love to see an example of changing the line search type while using DMDA/SNES.<br>

I suspect that I've made an error in the analytical Jacobian, which has a rather large number of non-zero elements, but I have no idea how to use -snes_type test -snes_test_display. The FAQs mention that some troubleshooting tools are more useful for small test problems. How small is small?<br>

If I instead use -snes_mf, the problem seems to converge, but horrendously slowly (true residual relative decrease by about 1e-5 per iteration). I suppose this supports my suspicion that the Jacobian is incorrect but doesn't really suggest a solution.<br>
