Dear GetFEM++ Project Sorry to ask many question. I want to ask about regular expression. When using "Grad_" in regular expression in 3D MeshFem. It seems that it create 3D tensor. My question is that the meaning of line and column. In my forecast, the line is the direction of variable and column is the direction of gradient. Is it correct? Is there any related part in the document? Thank you for reading.
Best Regard Tetsuo.
