Simcenter 3D

---------------

When solving some models containing beam elements, user could get Tosca error,

reporting some elements which are not supported for topology optimization with

the sensitivity based algorithm.

BEAM elements were defined as design variables (Design area and restricted

area).

The following messages were outputted when Topology Optimization was performed

using 1D element.

> **** TOSCA Structure ERROR ****

> Elementgroup used for TOPOLOGY OPTIMIZATION contains some elements

> which are not supported for topology optimization with the

> sensitivity based algorithm.

> Please check definition of the design variables and remove the

> elements from the list of elements used for topology optimization.

Beam elements within the design domain are not supported by Tosca Structure's

topology optimization.
