Hi guys!
I would like to import approximated polynomial velocity field (polynomial function with factors) from stereoscopic piv measurements. I want to use this velocity distribution as an inlet BC to test simulation performance for swirling flow. Is there a possibility to adress every velocity component with a 2d polynom fit function separately? e.g. like that x = x-coordinate y = y-coordinate component is scalar value of polynomial fit component = c1+c2*y+c3*x+c4*y^2+c5*x*y+c6*x^2; If seen the following in the documentation for polynomial fitting in 1d but i need help to adapt this to a 3d problem: uniformValue polynomial // y = 0.1 + 1.3x^2 + 2.7x^3 ( (0.1 0) (1.3 2.0) (2.7 3.0) ); Thanks in advance for your help! |
