I'm sorry I'm late to this thread.
My name is Guy Wills and I'm the Product Manager for the Topology Optimization applications.
We have NOT yet released a compatible version of this application for the Jan 2019 release. This has unfortunately been delayed, and I do understand the need to have this available ASAP.
Is Topology optimization supposed to work in 1851?
Got this error "Frustum core license check failed" in this file "\FrTemp\zqp1soci\output\info.log".
In splm_ugslmd.log "sc_des_topol_opt" is checked out.
