Open Dlubal CALC

Connector and MCP versions

Keep the Dlubal-Connector current and you do not need this page: CALC offers the update in the RFEM menu, and Restore connection to RFEM installs it. This page is for the case where an older installation cannot be updated right away and you want to know what it can and cannot do.

Which version you have

Settings → MCP servers shows both numbers on one line, for example Dlubal-Connector 2.28.8 · MCP 1.0.11. The second number is the MCP server that is actually running. When it differs from the expected one it turns amber: The version says one thing and behaves like another.

Example: Settings shows Dlubal-Connector 2.29.5 · MCP 1.0.14, and the folder icon for the local project folder asks for an update. Cause: linking a project folder needs Connector 2.30.3 or newer. Check: update the Connector from the RFEM menu, then open the project properties again.

The MCP server is the component the Connector installs and starts to talk to RFEM. It is updated together with the Connector.

1.0.14Separate read, restricted write and administrator permissions, Python tools off by default: Working with RFEM
1.0.14A calculation can target a model by its unique ID; restricted model creation only creates new models: Running calculations
1.0.14Packages live in a separate user directory and an update waits until no operation is running: First-time setup
1.0.16Releases an operation record without a confirmed outcome by itself once the RFEM session that ran it has ended: no confirmed outcome
