Dear Mr./Miss.,
In topology optimization, different initial guess may result in different final topologies. In COMSOL “topology optimization node”, if initial value of the design variable theta==1, which means at the starting point, the value of theta within the entire design domain remains the same.
My enquiry: Is it possible to start the optimization with a prescribed initial design?
For instance, in fluid topology optimization problem, instead of being initiated with a uniform theta==1 (fluid), how could I use a traditional parallel channel as an initial guess? The parallel channel layout can be accessed in the attached figure, please kindly check the attachment.
Best regards, Hao LI
