I disagree. CW can accurately analyse cylindrical-symmetric models in pie sectors, if it is restrained properly.

The key is restrained properly. The only way you can do this is to have the same node pattern on both symmetry faces and to have the displacements coupled between the nodes on those faces. Even Cosmos/M has trouble with this.

There are a few special cases where CosmosWorks will get this right. But in general CosmosWorks, Cosmos Simulation and DesignStar will not do this correctly.
