Hello everyone,  
I have a problem with optimization plugin Galapagos which doesn’t wait for the final result and before the fitness value is even calculated, Galapagos moves the sliders and a new configuration has to be evaluated. In this case cmd window opens two times for Meshing but Galapagos doesn’t wait for calculating the result.
