Thank you again! I will try to use non-iterative gradients calculation and I will let you know!

Thank you Yvan! Using the non-iterative gradient calculation decreased the calculation time of 25%! Very precious tip!!!!

As steated in the previous post the calculation time decreased a lot but now at the outlet I can se some unphisical behaviour (checkerboard). I used a non-iterative LS method. What is the cheapest way of calculating gradients that doesn't give this kind of problems?

Thanks again,
Luca

Hello,

The checkerboard should not happen in any case. Are you running in parallel ? If I remember correctly, there was a bug in 2.2.0 for some variant of the vector gradient, so upgrading to the latest 2.2.3 or 2.3.3 (or better, 3.0-beta) might help. A new 3.0-beta will probably be released this afternoon or tomorrow.

Regards,

Yvan

Dear Yvan,
yes, I'm running in parallel...Thanks for the information I will upgrade to 3-beta as soon as I can!
Thanks,
Luca
