Large-scale and Efficient Topology Optimization Approaches

1st Thematic Session @ 6th TOP Webinar –

October 29, 2020, Thursday, CET* (UTC+1:00) 16:00-17:30.

We are pleased to announce the program for the first thematic session on Large-scale and efficient topology optimization (TO) approaches at the sixth edition of the TOP Webinar (, scheduled for October 29, 2020, Thursday, CET 16:00-17:30. The thematic session covers several sub-topics and we will hear of Large-scale TO using high performance computing, Large-scale TO using sparse grids, efficient TO in Matlab and how to treat hundreds of millions of local constraints. There will be plenty of time for Q&A after the presentations and we are looking forward to seeing all of you there!

* Please note this time in your time zone might be different from previous TOP Webinars, due to the transition from European daylight-saving time. For your reference, CET 16:00 on Oct 29th is 8:00 Los Angeles, 11:00 New York, 23:00 Beijing, 2:00 (+1) Sydney.
