Level Set Method (Beta)
A new topology optimization algorithm based on the level set method.
Level-set based topology optimization can be considered as advanced shape optimization. It works like conventional shape optimization, where the design is changed by moving the boundary, while at the same time topological changes, such as boundary emerging and splitting can be handled naturally.
Level-set Optimization Setup
Guide to setup Level-set Optimization.
- Level-set Optimization is OFF by default for topology optimization in OptiStruct.
- It can be switched ON by adding the
LEVELSET continuation line on the
DTPL entry.
(1) (2) (3) (4) (5) (6) (7) (8) (9) (10) DTPL 1 PSHELL 7 8 17 LEVELSET ALIGN - An example input DTPL entry is shown above. This will activate the Level-set method for topology optimization. The fields on the LEVELSET continuation line can be used to control the implementation. Refer to DTPL Bulk Data Entry for further information.
