  1. Can somebody explain the details about optistruct algorithms 1. MFD 2. SQP 3. DUAL 4. DUAL2 5. BIGOPT which is most preferable for respective type of optimization like topology, topography, free size and shape.
  2. Hello community, I got a little bit confused while reading the OptiStruct 2017 User’s Guide. There I found that OptiStruct selects automatically the best optimization algorithm. Five items have been listed there (page 10-11): - Optimality criteria method - Convex approximation method - Method of feasible directions - Sequential quadratic programming - Advanced approximations . My question is: Does OptiStruct still selects the Optimality criteria method automatically? And for which type of optimization? There is no information about it in the User’s Guide or Reference Guide. I want to optimize the topology of the 2 dimensional MMB-Beam (see atteched figure). My objective is to minimize compliance subjected to a volume fraction constraint. I found that for my type of problem I shoud use 'OPTMETH=DUAL' since I have a large number of design variable and only one constraint. So I cannot choose the Optimality criteria method in topology optimization? Many thanks in advance Nahid
  3. Hi, I have an algorithm for the assignment of mobile stations in WinProp and I am struggling in adding this algorithm to the software. I have read the part of the manual where it shows the API Functions (which by the way I cannot find the NetManTrafficCore.pp file), that are used in Visual Studios but I still don't understand how to implement my own algorithm in WinProp. Also, where can I find the Visual Studio library that will help me in writing the algorithm? Can anybody help with details please? Thanks.
