I wrote a script to do that, but Mechanical and/or Workbench crashes as soon as the number of parameters is more than 40-50

I use a workaround by not using at all the Parameter module of Workbench and doing everything through ACT scripts, a bit painful though.

Coming from Comsol where it is so simple to define a global parameter and use it everywhere in a model, I am perplex on why such a functionality is not implemented in Workbench.
