[Tochnog-users] elastic deformation model

[U-E59264-Osman F B. <ab...@c1...>]

Hello,
  A few remarks:
1). I would start with a much smaller model at first. Then use mesh
refinement if possible. 40000 element model is large for tochnog.

2). Use the SUPERLU solver (serial version at first). Much faster for
larger problems. You will need to install that, and recompile tochnog.

3). 
control_timestep  520  1. 2.
control_timestep_iterations_automatic 520 0.1 10 

The last item in control_timestep_iterations_automatic is maximum
timestep. Since you are starting with time step size of 1 (from 0) and 
going to 2, 10 fox max step size doesn't make sense. Maybe set to 1?

4). if this is large deformation problem there will be a few
iterations. It is better if you start with "linear" run with one
timestep just to debug the model. 

Again, smaller is better (at least initially).

Best Regards,
Osman
