How to save Yams Parameters 
===========================

As Yams hypothesis are not meshing hypothesis for Salome (but hypothesis for yams), parameters
are stored in a special file. Default file is $HOME/.yams.dat. It is strongly recommended that you
change this name if you want to preserve the way you obtain a mesh : This file is never cleaned.
All sets of parameters are logged in it.


- To save the current setting, click on "Save Params" pushbutton. 
- A set of parameters is automatically written in the .yams.dat file when you run computation.  
- Restoring the default settings can be done by pushing "Default Params". 
- "Loading Params" will reload the last set of parameters
