### Detectors in transient simulations

Posted:

**Tue Apr 17, 2018 12:53 pm**Dear colleagues;

I'm running a transient simulation of a Minicore, starting from nominal power and then performing some rho insertions (namely moving some CR). To get my results I'm including two detectors to get the total power and some profiles (covering all the geometry), namely:
I suppose that the sum over all bins in det 2 should be the same as det 1, but I found a difference such as:
It doesn't look like a lack of convergence (each bin of det 2 reports a stdev of ~4%). Maybe some CFE params?

I also checked the same for critical calculations and in such case both detectors agree (det1 1 vs sum over all bins in det2). I''m missing something in dx dy dz when using di? Anyone experienced similar problems?

Thanks,

Diego

Code: Select all

```
det 1 dr -8 void di dettime
det 2 dr -8 void dx -31.72 31.72 45 dy -31.72 31.72 45 dz -182.88 182.88 10 di dettime
```
