Generally topology optimization gives an optimal material distribution of a design domain while minimizing the compliance of the structure. In this work focus has been kept on some practical design domains to get the actual structures after topology optimization using finite element solver ANSYS. ANSYS employs topology optimization using the Solid Isotropic Material with Penalization (SIMP) scheme for the penalization of the intermediate design variables and the Optimality Criterion for updating the design variables. 8 node 82 and solid 95 elements are used to model and mesh the isotropic structures in ANSYS.
