EMWorks Xpress is a free fully functional first-pass electromagnetic simulation tool. You can use EMWorks Xpress to perform basic electrostatic, magnetotstatic, and S-parameters analysis. You can easily study the effect of voltages on insulators, permanent magnets and coils on ferromagnetic core, and the frequency response of RF and Microwave devices. You can quickly determine and visualize design parameters such as electric field, voltage, magnetic flux density, magnetic field, and scattering parameters as well as generate both html and Word reports to document your work. As a free package, EMWorks Xpress comes with some limitations. However it offers enough functionality for carrying out basic analyses while giving the user a feel of the full versions of the company's flagship products EMS and HFWorks.
