Class PropertyTableRunner

java.lang.Object
neqsim.mcp.runners.PropertyTableRunner
public class PropertyTableRunner extends Object
Stateless property table runner for MCP integration.

Sweeps temperature or pressure over a range and returns a table of thermodynamic and transport properties at each point. This is the "one-shot engineering answer" tool that external agents need most often — no process flowsheet construction required.
