FAQ
ParticipantThis can be resolved by copying the lines: RULES: PARAMETER: Outer Radius of Injection Plane Dependency List = t Single Valued = true END PARAMETER: Inner Radius of Injection Plane Dependency List = t Single Valued = true END END into a file, e.g. rules_pir.ccl, and starting the solver with the solver option: -ccl rules_pir.ccl
