About CST Studio Suite
CST Studio Suite is a high-performance 3D EM analysis software package for designing, analyzing, and optimizing electromagnetic (EM) components and systems. Developed by Dassault Systèmes, it offers a powerful simulation platform for all electromagnetic field problems across the entire spectrum.
High-Frequency Simulation
The suite provides industry-leading tools for the calculation of electromagnetic high-frequency fields. Utilizing both Time Domain and Frequency Domain solvers, it enables the analysis of antennas, filters, couplers, and planar and multi-layer structures. It is particularly effective for evaluating Signal Integrity (SI), Power Integrity (PI), and Electromagnetic Compatibility (EMC).
System and Circuit Integration
Beyond standalone component simulation, the platform includes a dedicated environment for system-level integration. Users can connect various model components as building blocks via schematic circuits. This allows for the sophisticated coupling of electromagnetic components with active and passive circuit elements, enabling comprehensive co-simulation workflows.
Visualization and Modeling
CST Studio Suite features an intuitive graphical user interface that simplifies the creation of complex 3D geometries. It provides rich visualization tools for 2D and 3D field distributions, current densities, and far-field patterns. Results can be analyzed through automated post-processing templates, 1D plots, and animated field sequences to gain deep insight into device performance.

Extract from the CST STUDIO SUITE license agreement
The SCC has purchased a "Limited University Research License" from CST AG. According to CST AG , the following use is permitted with a "Restricted university research license." permitted:
"...
§ 2 Granting of rights
(1) CST grants Licensee the non-exclusive, non-transferable limited right to use the Contract Software within the scope of its university operations in accordance with the following provisions. The time limit and thus the permissible period of use is determined in the relevant CST offer accepted by Licensee for the license number stated in the contract header. 2.
If the right acquired by Licensee is designated in the accepted CST offer as a "SchoolLicense" or as a "Restricted University Research License", Licensee is permitted the non-commercial use of the Contract Software within the scope of its teaching and internal research operations. The research results obtained with the aid of the contract software must be accessible to the public immediately after their development. The Licensee is not permitted to make any further use of the Licensed Software. Any use of the Licensed Software by the Licensee beyond the aforementioned restrictions, in particular for external research operations, i.e. in cooperation with third parties, as well as for other purposes that are directly or indirectly related to a research contract of a third party or another contractual relationship between a third party and the Licensee that is associated with an economic advantage of any kind for the Licensee, shall be considered as further use. In this context, the acquisition of funding of any kind with the aid of the Contract Software shall also be deemed to be an economic advantage for the Licensee. 3.
If the right acquired by the Licensee is designated as an "Extended University Research License" in the accepted CST offer, the Licensee shall be permitted to use the Contract Software on a non-commercialbasis within the scope of its teaching and internal and external research operations, i.e. also in cooperation with third parties. The Licensee may derive economic benefits within the meaning of paragraph 2 from the cooperation with third parties, provided that no commercial use by the Licensee is associated therewith (e.g. marketing of research results, distribution of products derived from research results, etc.). The research results obtained with the aid of the contract software must be accessible to the public immediately after their development. The Licensee is not permitted to make any further use of the Contract Software. Any use of the Contract Software by the Licensee beyond the foregoing restrictions shall be deemed to be further use, in particular if such use is directly or indirectly in connection with proprietary research in the Licensee's own interest or on behalf of third parties. Proprietary research shall be understood to mean any form of research whose results are not intended to be made available to the public, at least in part, or only with a time delay (e.g. contract research for confidential industrial projects). 4.
(4 ) The right of use granted by this Agreement is limited to use by members of the Licensee's university staff. The contractual software may only be used locally within the facilities of the Licensee's university. In addition, use is also permitted outside the facilities of the Licensee's university, provided that the use takes place at purely scientific events (e.g. at university congresses, symposia, etc.). Any use beyond the above local restrictions requires the prior consent of CST. Third parties are not entitled to use the Contract Software. 5.
(5 ) If a person entitled to use the Contract Software under this Agreement performs other activities in addition to his or her activities at the Licensee's university, the Licensee shall not permit him or her to use the Contract Software in connection with such other activities.

The complete contract and the general terms of use can be found on the FTP server ftp://ftp.scc.kit.edu/pub/campus/CST_Studio_Suite/ and on the website of CST AG http://www.cst.com/Content/Company/Terms.aspx.
Addition to the license agreement of CST AG on 15.07.2013:
"... The terms and conditions defined in our University License Agreement apply solely to the use of the "restricted university research license" and not to the institution itself. This essentially means that it is irrelevant whether KIT consists of merged and no longer separable organizational units, but solely for what purpose the software licenses are used. ...
Paragraph §2, section 2 defines the conditions of the "Restricted University Research License", which excludes use in external research operations, i.e. in cooperation with third parties, as well as for other purposes [...]. This also applies to the acquisition of funding of any kind [...].
Paragraph §2, section 3 shows the possibility of an "Extended University Research License". With this license type, the use of the software in funded projects, such as DFG projects, is allowed under the condition that the results are made publicly available and are not subject to a confidentiality agreement. Accordingly, should simulations be performed in DFG projects, an additional (temporary) extended university research license would need to be purchased for just that purpose ..."
