Thomas, thank you for 3D case example,tzwinger wrote: ↑06 Oct 2021, 20:26 Hello,
If it helps, please find attached a similar case like the 2D test-case in 3D (runs on my gaming PC with 16 GB RAM and 6 core i5). Picture shows timestep of max. deformation:

Mind, to first create mesh-file (keeping in mind, that one has to move from kilometres to metres):
(mind, my computer has 6 cores, change the last number accordingly to your hardware)Code: Select all
gmsh -3 duallayer3d.geo ElmerGrid 14 2 duallayer3d.msh -autoclean -scale 1000 1000 1000 ElmerGrid 2 2 duallayer3d -partdual -metiskway 6
Best wishes,

it is good work in my PC for "Linear System Convergence Tolerance = 1.0e-07",
but if i replace mesh by mine mesh, which is complicate at the top middle part and try use solver with:
" Linear System Solver = Direct
Linear System Direct Method = MUMPS
Linear System Symmetric = Logical True"
ten years loading computation take about 10 minutes.
Then i am using:
" Linear System Solver = Iterative
Linear System Iterative Method = GCR
Linear System Max Iterations = 6000
Linear System Preconditioning = BILU2
Linear System Convergence Tolerance = 1.0e-05"
ten years loading computation take about 3-4 minutes, at the begining of iterations it is require more 2500 iteration but then decrease to less then 200 - 150 iterations. But under "iterative solver system" i couldn't increase convergence tolerance to 1.0e-07.
Thank you again.
