Hello [@itascan](https://forum.itascainternational.com/groups/itascan) [@everyone](https://forum.itascainternational.com/groups/everyone),  
My model is taking so long to reach to initial equilibrium state in FLAC 3D… Is there any way to reach the convergence faster apart from changing the convergence criteria itself?

@Newuser  
This is a very general question from which it is very hard to give you a helpful answer.  
For example, it is very possible (and if your problem is the initial equilibrium I would assume very probable) that there is some mistake in your boundary conditions and/or initial conditions. Therefore it is possible that the code has to make a lot of calculation steps to relax the model and even then a problem in the boundary conditions can lead to a “wrong” equilibrium.

Again, its hard to tell without any details, but I would suggest you check your setup. When properly configured and initialized, the initial equilibrium should usually only take a few steps.
