#1841: GRHydro tracers broken -----------------------------------+---------------------------------------- Reporter: I.Hawke@… | Owner: Type: defect | Status: new Priority: unset | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: GRHydro | -----------------------------------+---------------------------------------- The GRHydro::GRHydro_tracers group is not registered as a constrained variable with MoL in GRHydro. This means that, in runs with insufficient conserved variables and other memory settings, the first step through the loop sets NaNs for the tracers: they then fail to update (or, at least, not correctly).
To fix this, add
register_constrained("GRHydro::GRHydro_tracers");
on or around line 143 of GRHydro_RegisterVars.cc.
