The .HM.conn.cmf file is a HyperMesh command file.

File Creation

The .HM.conn.cmf file is created when a topology optimization is performed and 1D elements form part of the topological design space (see Topology Optimization in the OptiStruct User's Guide).

File Contents

When executed in HyperMesh, the .HM.conn.cmf file creates connector definitions for those 1D elements which formed part of the topological design space and organizes these connectors into ten new components based on their material densities at the final iteration. The components are named 0.0-0.1, 0.1-0.2, 0.2-0.3, and so on, up to 0.9-1.0. The connector corresponding to those elements with a material density between 0% and 10% are contained in the 0.0-0.1 component. The connectors corresponding to those elements with a material density between 10% and 20% are contained in the 0.1-0.2 component, and so on. This helps you to visualize results by turning components on and off.
