Manmit 0 Report post Posted May 13, 2018 Hello, I'm trying to use a nonlinear material (MATS1) in topology optimization which is resulting in the following error: *** ERROR # 4650 *** The design space for topology/freesize optimization can not contain nonlinear material. --- Is there any way to use a nonlinear material in topology optimization or is it currently not supported? I'm using HyperWorks 2017.2 with the following hotfixes: HyperWorks Desktop 2017.2.1 HyperWorks Solver 2017.2.2 Thanks in advance Manmit Quote Share this post Link to post Share on other sites
Guest Report post Posted May 14, 2018 Hi @Manmit Unfortunately, it is not possible to run topology optimization with non-linear materials. It is possible with RADIOSS integration (either use NLGEOM or check this tutorial on RADIOSS RD-E: 5100 Optimization in RADIOSS for B-Pillar (Thickness optimization)) Quote Share this post Link to post Share on other sites
