CID
Overview
Interactive program to simulate the cabling process, generate the geometry of a superconducting cable and calculate the electrical coupling parameters among superconducting strands (interstrand conductance and inductance). CID is a pre-processor extremely useful to facilitate the preparation of the input parameters for the simulation of electrodynamics and thermohydraulics of a cable using THEA. In addition it can be used to calculate the magnetic field and flux generated by the currents in each strand at user's specified locations in space, thus providing quantitative means to analyse experimental measurements of current distribution.
Details
- Generation and discretization of the 3-D geometry of a superconducting cable
based on simple commands and building blocks. The available cables geometries
can be used to generate twisted cables (ropes), core twisted cables (e.g. ropes
with central hollow space) and rutherford type cables.
- 3-D calculation of self and mutual strand inductances. The algorithm is
numerically efficient and stable.
- Line- and cross-contact model for the calculation of the interstrand conductance
matrix.
- 3-D field and vector potential calculation at arbitrary points in space, a useful
feature for the analysis and interpretation of measured data.
- Graphical User Interface with interactive plot, navigation and visualization modes for the 3-D cable geometry as well as the result of the electrical coupling parameters calculations.
Examples
The Graphical User Interface of CID is simple to use. Shown below is the geometry generated for a two-stage cable made of 3 x 4 twisted strands. The navigation tools are used to change the point of view of the 3-D model, that can be displayed in wireframe (transparent), hidden line or shaded view. Plots can be printed (generating PostScript files) for later use. Calculation results, such as interstrand inductance and conductance matrices, are available in a session log ASCII file.
