Has anyone used the 3D global convection model .prm file in the Heister2017？

ASPECT

Dear all,

I found Heister’s model and change it with ASPECT-version2.4.0.
Here is heister’s paper High accuracy mantle convection simulation through modern numerical methods – II: realistic models and problems | Geophysical Journal International | Oxford Academic, and it’s input file paper-aspect-methods-2-data/application/global_convection_3d.prm at master · tjhei/paper-aspect-methods-2-data · GitHub
I found it’s hard to slove after 30+Myrs, the time step become about 3000 yrs after 30+Myrs, it seems that this model wouldn’t end after 37600 CPU hours which is described in his paper(even won’t be end after 3700 time steps, because I run it about 1800 time steps only 39Myrs). I even used the “project q1 only viscosity” compared to his model, it should be more faster. it seems hard to solve after the plume were generated.
The addition files are my input file and logfile.

Dear Prof. Heister @tjhei

I also found your model videos on YouTube: https://youtu.be/LRs1Qdm-FSI

It’s so beautiful, do you have it’s input files for reference? I really want to learn ASPECT from your past .prm files. It will be very helpful for me.

I’ll also understand if you couldn’t share the .prm file with me. But I really want to know how to make the model converge more effectively, could you please give me some suggestion or informantion based on your model?(I always met the wrong cpu time even when I use the .prm file with your or Dr. Philip’s original input file). After all, It’s expensive for me to test these 3d global convection models.
