__Parameters__

CV-parameters that can also be set in UCV

This page is under development. The list of parameters will be completed gradually. Note:
  • Some CV-parameters (see common_variables) can also be set in USER_common_variables (UCV). The UCV-definition is dominant and overwrites the CV-definition (see warnings file in the simulation folder).

  • Some of these parameters can be set chamberwise, which can be necessary for multi-phase simulations. If such a parameter is not set for specific chambers, it is automatically set according to the non-chamberwise definition for all chambers.
