GlaDS--ElmerICE

Post by awhiteford » 19 Aug 2019, 05:32

Hi

When trying to run GlaDs and NS solvers I have convergence problems - the solution blows up.
The output reads "GlaDSCoupledsolver (hydraulic potential: Max S : -1.7976931348623157E+308 " and i get "Segmentation fault (core dumped)"
I have GlaDs running okay with static ice.

Are there any examples/tutorials available which run Glads and ice flow solvers?

Attached is my sif file, trying to run GlaDS on the teterousse mesh from the tutorials

Thanks,
Arran

Hi Arran,

I only see your message now. Did you solve your problem or is it still not working?

Regards,
Olivier

In general poor convergence can be due to too large a mesh size or too large a time step, or both.
