GRADIENTS
 
Hi all! I have a problem with gradients. Why using the coupled solver it's not possible to obtain the gradient? The solver gives me a segmentation error but gives no problem If I want to know the reconstructed gradient of the pressure. Please help. I hope somebody can gimme some suggestion. Luca

I had a similar problem. Are you shure that you use: solve/set/expert and "yes" answer to the question Keep temporary solver memory for beeing freed?

see UDF manual, pag 5-10

Yes I'm sure. Anyway I noticed the it works even if I don't set yes...it's strange, isn't it? I discovered that some gradients can be found, some others not...This happens even when I set the segregated.
