Bug #2236

Updated by dmitry over 1 year ago

To reproduce:

Create simulation with default GISAS instrument and default "Cylinders and prisms" sample.
Save simulation result, load it and set up fitting.
Try to fit beam intensity with e.g. Fumili algorithm chosen.

You will see a failure message (see screenshot)

Fails on the following algorithms:

Minuit2 - Fumili
GSL Levenberg-Marquardt
GSL MultiMin (only if start value is out of (min,max) range)
