Hi Chris,

The temperature at the bottom of the lake is too much. What do you think the problem is?

Cheers,

There can be many reasons for this, some ideas:

- incorrect inflow temperature data

- missing groundwater inputs

- too much mixing

Thanks For your answer,

I have no inflow and I am using 3 for default bc and 6 for iclousure. What would I change?

Unfortunately, this is not something anyone can just give a quick answer to.

This is the job of the modeller, to understand where the possible errors are coming from. You need to have an understanding of the system you are modelling and the boundary conditions you are forcing it with

Just circling back to this.  It was a CFL error. Timestep was too big.
