udf expression reqd
dear all,
i have in DPM for a 2D case du_dy = C_DUDY(cell, cthread); dv_dy = C_DVDY(cell, cthread); du_dx = C_DUDX(cell, cthread); dv_dx = C_DVDX(cell, cthread); if omega_c = (nabla) cross (u) where nabla is a gradient operator u = velocity of gas omega_c = rotational velocity of gas, what would be the expression of omega_c (both in x- and y-cordinates since i have 2D) i will be graetful if someone can giv me the expresison which i can use in the udf. kind regards. |
