Is there a faster way to restore the model's state?

[XiaoxuD]

Is there a faster way to restore the model's state to the end of the last step when conducting transient analysis?

I have use the "database, save and restore" to save the model's state in files. However, the speed of "save/restore" is too slow.
I wonder if there is a faster way.
Thank you.

Using RCM numberer will minimize the bandwidth of the stiffness matrix, it may help with making the state saving faster.

Also you can try UmfPack and SparseSYM solvers and see if they would help

to what end are you storing the state! .. the only alternative would be to recompute from the start.
