Fatal error E5000 for the linear static analysis

[saito.kousuke]

Hello all,

I have a simple cavity with two mirrors (see attached picture). the material of four rods are glass and the others are duralumin.

The purpose of this simulation is to see the displacement of cavity length due to thermal expansion , fixing the bottom faces of two feet completely. But I keep getting an E5000 singularity error. Fixing the bottom face doesn't suffice?

I was wondering if anyone would be able to show me the proper way to constrain this .

Thank you very much for the help.
