Embodiment Construction
[0141] The present invention will be further described below in conjunction with drawings and embodiments.
[0142] A method for isogeometric solution and heat dissipation topology generation of a heat flow strong coupling problem, comprising the following steps:
[0143] 1) Define design conditions:
[0144] Taking the two-dimensional miniature square flat plate structure as the design domain, the size parameter of the design domain is 0.01m×0.01mm, the uniform thermal load in the design domain is Q, the surrounding of the design domain is an adiabatic boundary, and the width of the entrance and exit is 0.001m, respectively located in the design domain In the middle of the left and right boundaries of , the uniform heat load in the design domain is Q=1×10 9 W / m 2 ,like figure 1 shown;
[0145] 2) Determine the design variables:
[0146] Take the elliptical bar component as the flow channel, and each component contains the coordinates of the center of the component (x 0 ...
