Lethal Temperature

Hi there
I would like to know how long a particle needs to be in an area of lethal temperature to be removed from the simulation?
Is it a timestep of the hydrodynamic model I'm using, or a timestep of the Ichthyop model that I set? Does the record frequency effect this?
Cheers

Dear Alice,

Lethal temperature check occurs at Ichthyop tim step. As soon as it faces cold/hot water it is removed from the simulation. The record frequency does not impact the lethal temperature detection thought it does impact when the end user sees the particle as dead cold (or dead hot).

Let me clarify : let's assume that a larva faces cold water at t0 + 17 time steps and the record frequency is set to 5 time steps. At time step t0+15 Ichthyop sees the larva as ALIVE. At t0+17 it is removed from the simulation. At t0+20 Ichthyop writes a new record in the NetCDF output file and the larva is tagged DEAD_TEMPERATURE. When you analyse the NetCDF output file, the only information you get is that sometime between t0+16 and t0+20 the particle has been removed from the simulation.

The only way to get the exact time step a larva is being removed from the simulation is to set the record frequency to 1.
